FIELD OF THE INVENTION

[0002]The present invention relates to novel bacterial isolates identified by their 16S rRNA DNA, that cause periodontal disease in companion animals, polynucleotide sequences contained therein, polypeptides encoded by such polynucleotide sequences and vaccines comprising such bacterial isolates that have been inactivated or attenuated, polynucleotides or polypeptides. Also provided are methods for treating and preventing periodontal disease and kits for detecting, treating, and preventing periodontal disease. In addition, methods for assessing the efficacy of a vaccine against periodontal diseases in an animal are provided.

BACKGROUND ART

[0003]The vast majority of experimental data concerning periodontal diseases is based on studies of humans or bacteria isolated from humans. Relatively little is known with respect to periodontal disease in non-human animals, such as companion animals, and in particular, dogs and cats.

[0004]Periodontal disease comprises a group of infections involving supporting tissues of the teeth. These range in severity from mild and reversible inflammation of the gingiva (gum) to chronic destruction of periodontal tissues (gingiva, periodontal ligament, and alveolar bone) with eventual exfoliation of teeth.

[0005]From a microbiological standpoint, several features of this disease are of interest. The bacterial etiology is complex, with a variety of organisms responsible for the initiation and progression of disease in humans. Many, if not all, of these organisms may also be present in periodontally healthy individuals and can exist in commensal harmony with the host. Thus, disease episodes may ensue from a shift in the ecological balance between bacterial and host factors, as a result of, for example, alteration in the absolute or relative numbers of certain organisms, changes in pathogenic potential, or modulation of particular host factors. The local environment imposes a variety of unique constraints upon the constituent microbiota of the supragingival tooth surface and the subgingival crevice (the channel between the tooth root and the gingiva that deepens into a periodontal pocket as disease progresses).

[0006]Both the calcified hard tissues of the tooth and the epithelial cells of the gingival are available for colonization. These tissues are exposed to host salivary secretions and gingival crevicular fluid (a serum exudate), both of which contain molecules that interact directly with bacteria and alter prevailing environmental conditions. In addition, it is known that in humans, successful colonizers of the teeth and subgingival area must coexist with many (over 600) other species of bacteria that inhabit these regions. Study of the pathogenesis of periodontal diseases in humans is thus complicated by the ecological intricacy of the microenvironment.

[0007]The classification of the various manifestations of periodontal disease in humans is continually changing, and it will suffice to mention that diseases range in severity, rate of progression, and number of teeth affected and that different age groups can be susceptible following the eruption of primary teeth. The nature of the pathogenic agents varies among these disease entities, as well as among human patients and even between different disease sites within a patient. In general, however, severe forms of the disease are associated with a number of gram-negative anaerobic bacteria. Of this group, in humans, most evidence points to a pathogenic role for Porphyromonas (formerly Bacteroides) gingivalis. The presence of this organism, acting either alone or as a mixed infection with other bacteria, and possibly in concert with the absence of beneficial species and certain immunological responses in the host, appears to be essential for disease activity.

[0008]Colonization of the oral cavity requires that the bacteria first enter the mouth and then localize at and attach to the available surfaces. Host factors which function to prevent bacterial colonization include the mechanical shearing forces of tongue movement along with saliva and gingival crevicular fluid flow. Successful oral colonizers therefore possess a variety of attributes to overcome host protective mechanisms. The sessite plaque biofilm that subsequently accumulates on the hard and soft tissues of the mouth is a dynamic system composed of diverse microbial species. In humans, P. gingivalis is usually among the late or secondary colonizers of the oral cavity, requiring antecedent organisms to create the necessary environmental conditions.

[0009]Initial entry of P. gingivalis into the human oral cavity is thought to occur by transmission from infected individuals. Other vectors would therefore also appear to be operational. These studies indicate that individuals are colonized by a single (or at least a predominant) genotype, regardless of site of colonization or clinical status. Strains of many different clonal origins, in contrast, are present in different individuals. This supports the concept that P. gingivalis is essentially an opportunistic pathogen, with virulence not being restricted to a particular clonal type.

[0010]The human oral cavity provides a variety of surfaces to which P. gingivalis can adhere. There are the mineralized hard tissues of the teeth, along with mucosal surfaces including those of the gingiva, cheek, and tongue.

[0011]While a great deal is known about periodontal disease in humans, as described above, very little is known about the same disease in companion animals. Fournier, D. et al., "Porphorymonas gulae sp. nov., an Anaerobic, Gram-negative, Coccibacillus from the Gingival Sulcus of Various Animal Hosts", International Journal of a Systematic and Evolutionary Microbiology (2001), 51, 1179-1189 describe several strains isolated from various animal hosts, including a strain, P. gulae spp. nov., designated ATCC 57100. The authors hypothesize that strains for the animal biotype of P. gingivalis represent a Porphyromonas species that is distinct from P. gingivalis. There is no mention of a vaccine useful in treating periodontal disease in companion animals. Hirasawa and Takada, in "Porphyromonas gingivicanis sp. nov. and Porphyromonas crevioricanis sp. nov., Isolated from Beagles", International Journal of Systemic Bacteriology, pp. 637-640, (1994), describe two bacterial species isolated from gingival crevicular fluids of beagles. These species are described in U.S. Pat. No. 5,710,039 and U.S. Pat. No. 5,563,063. Nowhere do the authors suggest the use of these species in a vaccine to treat periodontal disease. International Application PCT/AU98/01023, having publication number WO 99/29870, described various P. gingivalis polypeptides and nucleotides. However, no evidence of vaccines effective in preventing periodontal disease in companion animals is provided. Even though there is a great amount of information known about the human disease, little has been accomplished by way of preventing or treating the disease, even in humans.

[0012]There remains a need for a safe and effective vaccine for treating and preventing periodontal disease in companion animals.

[0013]Genco et al. (Trends in Microbiology 6: 444-449, 1998) describe a rat model for investigating Porphyromonas gingivicanis-mediated periodontal disease. Grecca et al. (J. Endodontics 27: 610, 2001) describe radiographic evaluation of periradicular repair after endodontic treatment of dog's teeth with induced periradicular periodontitis.

[0014]Prior to the present invention, there has been no animal model available for assessing the efficacy of a vaccine against one or more periopathogenic bacteria in a defined and quantitative manner.

In a preferred embodiment, the isolated bacteria of the present invention can be identified by their 16S rRNA DNA sequences shown in SEQ ID Nos. 86 to 94.

[0091]The diseases caused by infection with the bacteria of the present invention include, but are not limited to, companion animal periodontal disease, companion animal oral malodor (halitosis), bovine foot rot, canine coronary heart disease and canine systemic infections. Bacteria within the genus Porphyromonas have also been connected with various human diseases, including coronary heart disease, parotitis, oral malodor, gingivitis, periodontis, stroke, atherosclerosis, hyperlipidemia, bacterial vaginosis, intrauterine growth retardation (IUGR), and increased incidence of pre-term delivery of low birth weight infants.

[0092]The present invention provides isolated polynucleotide and isolated polypeptide molecules of Porphyromonas spp. More particularly, the invention provides isolated polynucleotide molecules having the nucleotide sequence of Porphyromonas spp. fimA and oprF genes or degenerate variants thereof and isolated polypeptide molecules having the amino acid sequences of the FimA and OprF proteins encoded by such genes, respectively.

[0093]The present invention also provides polynucleotide sequences having at least about 90% homology, preferably at least about 95%, and most preferably at least 99%, sequence identity to any of SEQ ID NOS: 95 to 102 and 111 to 119 as determined using any known standard identity algorithm. In addition, the present invention provides polynucleotide sequences that hybridize under stringent conditions to the complement of any of the polynucleotide sequences shown in SEQ ID NOS: 95 to 102 and 111 to 119.

[0094]In another specific embodiment, a nucleic acid which is hybridizable to any of the polynucleotide sequences depicted in SEQ ID No. 86 to 102 and 111 to 119, or their complements, under conditions of high stringency is provided. By way of example and not limitation, procedures using such conditions of high stringency for regions of hybridization of over 90 nucleotides are as follows. Prehybridization of filters containing DNA is carried out for 8 h to overnight at 65° C. in buffer composed of 6×SSC, 50 mM Tris-HCl (pH 7.5), 1 mM EDTA, 0.02% PVP, 0.02% Ficoll, 0.02% BSA, and 500 μg/mL denatured salmon sperm DNA. Filters are hybridized for 48 h at 65° C. in prehybridization mixture containing 100 μg/mL denatured salmon sperm DNA and 5-20×10⁶ cpm of ³²P-labeled probe. Washing of filters is done at 37° C. for 1 h in a solution containing 2×SSC, 0.01% PVP, 0.01% Ficoll, and 0.01% BSA. This is followed by a wash in 0.1×SSC at 50° C. for 45 min before autoradiography.

[0095]Other conditions of high stringency which may be used depend on the nature of the nucleic acid (e.g. length, GC content etc.) and the purpose of the hybridization (detection, amplification, etc.) and are well known in the art. For example, stringent hybridization of an oligonucleotide of approximately 15-40 bases to a complementary sequence in the polymerase chain reaction (PCR) is done under the following conditions: a salt concentration of 50 mM KCl, a buffer concentration of 10 mM Tris-HCl, a Mg²+ concentration of 1.5 mM, a pH of 7-7.5 and an annealing temperature of 55-60° C.

[0096]In a preferred specific embodiment, after hybridization, wash conditions are as follows. Each membrane is washed two times each for 30 minutes each at 45° C. in 40 mM sodium phosphate, pH 7.2, 5% SOS, 1 mM EDTA, 0.5% bovine serum albumin, followed by four washes each for 30 minutes in sodium phosphate, pH 7.2, 1% SDS, 1 mM EDTA. For high stringency hybridization, the membranes are additionally subjected to four washes each for 30 minutes in 40 mM sodium phosphate, pH 7.2, 1% SDS, 1 mM EDTA at 55° C., followed by four washes each for 30 minutes in sodium phosphate, pH 7.2, 1% SDS, 1 mM EDTA at 65° C.

[0097]The present invention further provides vaccines and vaccine formulations which, when administered to a companion animal in a therapeutically effective amount, are useful in treating or preventing (i.e., conferring resistance) to periodontal disease in a companion animal.

[0098]In one embodiment, the present invention provides a vaccine that comprises at least one attenuated (modified live) or inactivated whole cell Porphyromonas spp. preparation (bacterin). In a preferred embodiment the present invention provides a vaccine that contains an inactivated whole cell preparation of at least three Porphyromonas spp., for example, the combination of P. gulae B43, P. salivosa B104 and P. denticanis B106. The bacterial cells can be inactivated using a variety of agents, such as formalin, binary ethyleneimine (BEI) or beta-propriolactone. Preferably, formalin is used as the inactivating agent.

[0099]In another embodiment, the vaccine comprises a subunit fraction of a Porphyromonas spp. capable of inducing an immune response.

[0100]In a preferred embodiment the vaccine of the present invention comprises one or more subunit polypeptides or fragments or variants thereof or one or more isolated polynucleotide sequences or fragments or variants thereof.

[0101]The attenuated (modified live) or inactivated vaccines (bacterins), or isolated subunit polypeptides, or isolated polynucleotides can be present in combination with other known vaccine formulation components such as with compatible adjuvants, diluents, or carriers.

DEFINITIONS AND ABBREVIATIONS

[0102]The term "ORF" indicates "open reading frame", i.e. the coding region of a gene.

[0103]The term "Percentage of sequence identity" for nucleotide sequences and polypeptide sequences is determined by comparing two optimally aligned sequences over a comparison window, wherein optimal alignment provides the highest order match and can introduce nucleotide or amino acid additions or to the test or reference sequence. The percentage identity is determined by calculating the percentage of nucleotides-that are identical between the test and reference sequence at each position over the entire sequence. Optimal sequence alignment and percentage identity can be determined manually, or more preferably by a computer algorithm including but not limited to TBLASTN, BLASTP, FASTA, TFASTA, GAP, BESTFIT, and CLUSTALW (Altschul et al., 1990, J. Mol. Biol. 215(3):403-10; Pearson and Lipman, 1988, Proc. Natl. Acad. Sci. USA 85(8):2444-8; Thompson, et al., 1994, Nucleic Acids Res. 22(22):4673-80; Devereux et al., 1984, Nuc. Acids. Res. 12:387-395); Higgins, et al., 1996, Methods Enzymol. 266:383-402).

Isolation and Characterization of Porphyromonas spp

[0123]Bacteria provided by the present invention can be obtained using known sampling, culture and isolation techniques. For example, microbial samples can be obtained from a population of companion animals, such as from dogs and cats, exhibiting periodontal disease. Evidence of periodontal disease can be observed using known measures, such as dogs with periodontal pockets >3 mm and cats with periodontal pockets >2 mm. Known parameters for characterizing periodontal disease such as dental indices (gingival index and periodontal index) and periodontal pocket depths can determined for the sample population of companion animals. Individual samples can be obtained from the periodontal pocket of a particular animal, maintained under anaerobic conditions and cultured using various known culture media.

[0124]Clinical isolates can be characterized using known techniques such as a number of biochemical tests, and 16S rRNA DNA sequence analysis to determine their genus and species. Individual isolates can be transferred to plates and antibiotic disks (Anaerobe Systems) can be placed on the agar surface to determine the antibiotic resistance patterns of each isolate. Purified colonies can also be subjected to known indole and catalase tests (Anaerobe Systems). Lipase and lecithinase production patterns can be determined for individual isolates.

[0125]The isolates can be typed based on their 16S rRNA DNA sequence. Individual, well-isolated colonies can be utilized as a template for polymerase chain reactions (PCR) amplification of the 16S rRNA region using, for example, primers D0056 and D0057 (Seq. ID NO. 1 and Seq. ID NO. 2; Table 1). The resulting PCR products can be purified using available PCR preps kits (Promega Corp.; Madison, Wis.) and pooled by isolate. The purified PCR products can then be desalted and subjected to DNA sequence analysis. The resulting DNA sequences can be used to search available DNA databases. The bacterial isolates can then be typed based on the closest match identified by database searches.

The preferred polypeptides of the present invention have amino acid sequences selected from the group consisting of SEQ ID NOS: 103 to 110 and 120 to 128.

Cloning of Porphyromonas Nucleotide Sequences

[0127]There are several known methods or techniques that can be used to clone the Porphyromonas nucleotide sequences of the present invention. For example, the sequences can be isolated as restriction fragments and cloned into cloning and/or expression vectors, the sequences can be PCR amplified and cloned into cloning and/or expression vectors, or the sequences can be cloned by a combination of these two methods.

[0128]Standard molecular biology techniques known in the art and not specifically described can be generally followed as described in Sambrook et al., Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory Press, New York (1989); Ausubel et al., Current Protocols in Molecular Biology, John Wiley and Sons, Baltimore, Md. (1989); Perbal, A Practical Guide to Molecular Cloning, John Wiley & Sons, New York (1988); Watson et al., Recombinant DNA, Scientific American Books, New York; Birren et al (eds) Genome Analysis: A Laboratory Manual Series, Vols. 1-4 Cold Spring Harbor Laboratory Press, New York (1998); and methodology set forth in U.S. Pat. Nos. 4,666,828; 4,683,202; 4,801,531; 5,192,659 and 5,272,057. Polymerase chain reaction (PCR) is carried out generally as described in PCR Protocols: A Guide To Methods And Applications, Academic Press, San Diego, Calif. (1990).

[0129]Examples of methods useful in cloning and sequencing the polynucleotides. of the present invention are provided in the Example.

fimA and oprF-Encoded Polypeptides and Proteins

[0130]The present invention encompasses the use of prokaryotic and eukaryotic expression systems, including vectors and host cells, which may be used to express both truncated and full-length (native protein) forms of the recombinant polypeptides expressed by the nucleotide sequences of the present invention.

[0131]In a preferred embodiment of the invention, an isolated polynucleotide molecule of the present invention has a nucleotide sequence selected from one of the sequences of SEQ ID NO: 95 to 102 and 111 to 119 or degenerate variants thereof; and encoding a corresponding polypeptide selected from the amino acid sequences of SEQ ID NO: 103 to 110 and 120 to 128, respectively.

[0132]A variety of host-expression vector systems may be utilized to express the polypeptides of the present invention. Such host-expression systems also represent vehicles by which the coding sequences of interest may be cloned and subsequently purified. The present invention further provides for host cells which may, when transformed or transfected with the appropriate vector or nucleotide sequence, express the encoded polypeptide gene product of the invention. Such host cells, include but are not limited to, microorganisms such as bacteria (e.g., E. coli, B. subtilis) transformed with recombinant bacteriophage DNA, plasmid DNA or cosmid DNA expression vectors containing coding sequences; yeast (e.g., Saccharomyces, Pichia) transformed with recombinant yeast expression vectors containing the gene product coding sequences; insect cell systems infected with recombinant virus expression vectors (e.g., baculovirus) containing the coding sequences; plant cell systems infected with recombinant virus expression vectors (e.g., cauliflower mosaic virus, CaMV; tobacco mosaic virus, TMV) or transformed with recombinant plasmid expression vectors (e.g., Ti plasmid) containing coding sequences; or mammalian cell systems (e.g., COS, CHO, BHK, 293, 3T3) harboring recombinant expression constructs containing promoters derived from the genome of mammalian cells (e.g., metallothionein promoter) or from mammalian viruses (e.g., the adenovirus late promoter; the vaccinia virus 7.5K promoter).

[0133]In a preferred embodiment, the expression system is a bacterial system. A number of expression vectors may be advantageously selected depending upon the use intended for the product being expressed. For example, when a large quantity of such a polypeptide is to be produced, for the generation of vaccine compositions or for raising antibodies, for example, vectors which direct the expression of high levels of fusion protein products that are readily purified may be desirable. Preferably, the vectors contain promoters that direct inducible gene expression. Suitable vectors include, but are not limited to, the E. coli pET expression vectors (Studier and Moffatt, 1986, J. Mol. Biol. 189:113; Rosenberg et al., 1987, Gene 56:125-135; Novagen, Madison, Wis.), in which the coding sequence can be fused in-frame to a sequence encoding multiple (e.g., 6) histidine residues; pBAD vectors (Guzman et al., 1995, J. Bact. 177:4121-4130), from which a heterologous protein can be expressed under the control of an arabinose inducible protein; and pGEX vectors (Pharmacia Biotech, USA), used to express heterologous polypeptides as fusion proteins with glutathione S-transferase (GST). The fimA or oprF sequences of the present invention can be cloned into a λ expression vector and expressed in λ.sup.- bacterial strains. In a preferred mode, the bacterial strain is E. coli BL21 (Gibco-BRL, USA). Preferably, the vectors that can be used include, but are not limited to, pLEX expression vectors (LaVallie et al., 1992, Bio/Technology 11:187-193; Mieschendahl et al., 1986, Bio/Technology 4:802-808; Invitrogen) and pRIT2T expression vectors (Nilsson et al., 1985, EMBO 4:1075; Zabeau and Stanley, 1982, EMBO 1:1217; Pharmacia Biotech). Other vectors and bacterial strains can be used and are known to those skilled in the art.

Antibody Production

[0134]Antibodies may either be monoclonal, polyclonal, or recombinant. Conveniently, the antibodies may be prepared against the immunogen or portion thereof, for example, a synthetic peptide based on the sequence, or prepared recombinantly by cloning techniques or the natural gene product and/or portions thereof may be isolated and used as the immunogen. Immunogens can be used to produce antibodies by standard antibody production technology well known to those skilled in the art as described generally in Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., 1988 and Borrebaeck, Antibody Engineering--A Practical Guide, W.H. Freeman and Co., 1992. Antibody fragments may also be prepared from the antibodies and include Fab, F(ab')₂, and Fv by methods known to those skilled in the art.

[0135]In the production of antibodies, screening for the desired antibody can be accomplished by standard methods in immunology known in the art. Techniques not specifically described are generally followed as in Stites et al. (eds), Basic and Clinical Immunology (8th Edition), Appleton & Lange, Norwalk, Conn. (1994) and Mishell and Shiigi (eds), Selected Methods in Cellular Immunology, W.H. Freeman and Co., New York (1980). In general, ELISAs and Western blotting are the preferred types of immunoassays. Both assays are well known to those skilled in the art. Both polyclonal and monoclonal antibodies can be used in the assays. The antibody can be bound to a solid support substrate or conjugated with a detectable moiety or be both bound and conjugated as is well known in the art (for a general discussion of conjugation of fluorescent or enzymatic moieties see Johnstone & Thorpe, Immunochemistry in Practice, Blackwell Scientific Publications, Oxford, 1982.) The binding of antibodies to a solid support substrate is also well known in the art (see for a general discussion, Harlow & Lane Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Publications, New York, 1988 and Borrebaeck, Antibody Engineering--A Practical Guide, W.H. Freeman and Co., 1992). The detectable moieties contemplated for use in the present invention can include, but are not limited to, fluorescent, metallic, enzymatic and radioactive markers such as biotin, gold, ferritin, alkaline phosphatase, b-galactosidase, peroxidase, urease, fluorescein, rhodamine, tritium, ¹⁴C and iodination.

[0136]Where appropriate, other immunoassays such as radioimmunoassays (RIA) can be used as known in the art. Available immunoassays are extensively described in the patent and scientific literature. See, for example, U.S. Pat. Nos. 3,791,932; 3,839,153; 3,850,752; 3,850,578; 3,853,987; 3,867,517; 3,879,262; 3,901,654; 3,935,074; 3,984,533; 3,996,345; 4,034,074; 4,098,876; 4,879,219; 5,011,771; and 5,281,521, as well as Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Springs Harbor, N.Y., 1989.

Detection, Diagnostic, and Prevention Kits

[0137]The present invention further provides kits for the detection of Porphyromonas spp. The kit includes reagents for analyzing a sample for the presence of Porphyromonas organisms, polypeptides, or Porphyromonas nucleotide sequences of the present invention, wherein the presence of the nucleotide sequence is indicative of the presence of the organism. This method is valuable because disease can be diagnosed prior to the existence of symptoms and can therefore prevent the onset of the disease prior to the occurrence of damage to the patient. The presence of the Porphyromonas spp. Bacteria, polypeptides, or nucleotide sequences can be determined using antibodies, PCR, hybridization, and other detection methods known to those of skill in the art.

[0138]In one embodiment, the kit provides reagents for the detection of antibodies against Porphyromonas. In certain embodiments, the kit can include a set of printed instructions or a label indicating that the kit is useful for the detection of Porphyromonas spp. Minimally, the kit comprises in at least one container a protein having an amino acid sequence comprising at least 30 contiguous amino acids of any of the polypeptides of SEQ ID NO: 103 to 110 and 120 to 128. In one embodiment, the kit further comprises a secondary antibody.

[0141]The vaccine of the present invention can be is administered to a companion animal in an effective amount such that the vaccine therapeutically treats or confers resistance to or prevents periodontal disease in the companion animal. The vaccine of the present invention is useful in the control of bacteria that cause periodontal disease. The vaccines of the present invention can, in particular, be used in the field of veterinary medicine to treat companion animals and for the maintenance of public health against those bacteria described herein which are known to cause periodontal disease.

[0142]The vaccines of the present invention are of value in the control of bacteria that are injurious to, or spread or act as vectors of disease in man and companion animals, for example those described herein. The vaccines of the present invention are particularly useful in controlling bacteria that are present in companion animals for which purpose they can be administered using any known methods of administration, including, but not limited to, oral, parenteral, intranasal, subcutaneous, or topical.

[0143]According to a further aspect of the present invention, there is provided a composition comprising a vaccine of the present invention, in admixture with a compatible adjuvant, diluent or carrier. In a preferred embodiment, the vaccine formulation of the present invention is composed of an aqueous suspension or solution containing at least one bacteria of the present invention and/or at least one subunit protein, preferably buffered at physiological pH, in a form ready for injection. In another preferred embodiment, the vaccine formulation of the present invention is composed of inactivated whole cell preparations of at least three Porphyromonas spp., for example, P. gulae B43, P. salivosa B104 and P. denticanis B106.

[0144]The present invention further provides a method of treating or preventing a bacterial infection, which comprises treatment with an effective amount of a vaccine or vaccine formulation of the present invention. It is to be appreciated that reference to treatment includes prophylaxis as well as the alleviation of established symptoms of a bacterial infection.

[0145]The vaccines and vaccine formulations of the present invention can used to induce a response that prevents the pathological changes characteristic of periodontal disease caused by periodontal disease-causing bacteria. In a vaccine formulation, an immunogenic amount of the bacteria, purified protein, nucleic acid, or combinations thereof is desirably mixed with a suitable conventional vaccine adjuvants and physiologic vehicles, for use in mammals.

[0146]A vaccine formulation for preventing periodontal disease in companion animals can be produced using at least one of the isolated and purified inactivated or attenuated bacteria, purified polypeptides (such as native proteins, subunit proteins, or polypeptides, and admixing one or more or these with a compatible adjuvant, diluent, or carrier. Preferably, the polypeptide sequences are subunit proteins selected from the group including FimA (SEQ ID NOS: 103 to 110 and OprF (SEQ ID NOS: 120 to 128).

[0147]Examples of fragments of FimA and OprF that can be used for diagnostic polypeptides or for vaccine preparations include, but are not limited to ACNKDNEAEPVV, YPVLVNFESNNYTYTGDAVEK, TGPGTNNPENPITESA, NDNNNKDFVDRLGA, DLNGQINRLRREVEELSKRPVSCPECPDV, and ADPTGDTQYNERLSERRAKAV (SEQ ID NOS: 129-134). The subunit protein can be recombinantly expressed, either alone or fused to another polypeptide sequence or protein. The other polypeptide sequence or protein can include, but is not limited to, a poly-His tag, MBP, thioredoxin, or GST, for example. Also provided by the present invention are the polynucleotide sequences or genes that encode any of the above mentioned subunit proteins. The polynucleotide sequence of the bacteria can be selected from fimA and oprF or a fragment or variant thereof which fragment or variant exhibits at least about 90%, 95%, or 99% homology thereto, or a complementary polynucleotide sequence which hybridizes under high stringency conditions, or a combination of both. Preferably, the polynucleotide sequences of the present invention can be used to amplify a fimA or oprF DNA molecule of the present invention, or encodes an amino acid fragment than can be used to raise antibodies against FimA or OprF.

[0148]For DNA-based therapy, a vehicle capable of delivering or transferring heterologous nucleic acid into a host cell may be used. The expression vehicle may include elements to control targeting, expression and transcription of the nucleic acid in a cell selective manner as is known in the art. The expression vehicle can include a promoter for controlling transcription of the heterologous material and can be either a constitutive or inducible promoter to allow selective transcription. Enhancers that may be required to obtain necessary transcription levels can optionally be included.

[0149]Vectors can be introduced into cells or tissues by any one of a variety of known methods within the art. Such methods can be found generally described in Sambrook et al., Molecular Cloning: A Laboratory Manual, Cold Springs Harbor Laboratory, New York (1989, 1992); Ausubel et al., Current Protocols in Molecular Biology, John Wiley and Sons, Baltimore, Md. (1989); Chang et al., Somatic Gene Therapy, CRC Press, Ann Arbor, Mich. (1995); Vega et al., Gene Targeting, CRC Press, Ann Arbor, Mich. (1995); R. L. Rodriguez Vectors: A Survey of Molecular Cloning Vectors and Their Uses, Butterworths, Boston Mass. (1988) and include, for example, stable or transient transfection, lipofection, electroporation and infection with recombinant viral vectors.

[0150]The present invention further provides for combinations vaccines having at least one of the inactivated or attenuated bacteria, nucleotide sequences, or polypeptide sequences of the present invention, in combination with one or more additional immunogenic components. Such a combination vaccine may produce in the vaccinated animal a surprisingly greater effect than that expected by simply adding the effects of each component administered separately. Thus, a combination vaccine may stimulate a synergistic production of antibody in animals.

[0151]In a preferred embodiment, the combination vaccine of the present invention is composed of inactivated whole cell preparations of at least three Porphyromonas spp., for example, P. gulae B43, P. salivosa B104 and P. denticanis B106, in combination with one or more additional bacterial or viral immunogenic components. Additional immunogenic components suitable for use in combination vaccines of the present invention include, but are not limited to Canine Distemper Virus (CDV), Canine Adenovirus-2 (CAV-2), Canine Parvovirus (CPV), Canine Parainfluenza Virus (CPI), and Canine Coronavirus (CCV),

[0152]Vaccines of the present invention can be prepared by combination of at least one of the inactivated or attenuated bacteria, nucleotide sequences, or polypeptide sequences of the present invention, with a pharmaceutically acceptable carrier, an preferably, an adjuvant.

[0153]Suitable preparations of the vaccines of the present invention include injectables, either liquid solutions or suspensions. Solid forms suitable for solution in, or suspension in, a liquid pharmaceutically acceptable carrier prior to injection may also be prepared. The vaccine preparation may be emulsified. The active immunogenic component, is preferably mixed with an adjuvant which is pharmaceutically acceptable and compatible with the active immunogenic component. Suitable adjuvants include, but are not limited to: mineral gels, e.g., aluminum hydroxide; surface active substances such as lysolecithin; glycosides, e.g., saponin derivatives such as Quil A or GPI-0100 (U.S. Pat. No. 5,977,081); cationic surfactants such as DDA, pluronic polyols; polyanions; non-ionic block polymers, e.g., Pluronic F-127 (B.A.S.F., USA); peptides; mineral oils, e.g. Montanide ISA-50 (Seppic, Paris, France), carbopol, Amphigen (Hydronics, Omaha, Nebr. USA), Alhydrogel (Superfos Biosector, Frederikssund, Denmark) oil emulsions, e.g. an emulsion of mineral oil such as BayolF/Arlacel A and water, or an emulsion of vegetable oil, water and an emulsifier such as lecithin; alum, cholesterol, rmLT, cytokines and combinations thereof. The immunogenic component may also be incorporated into liposomes, or conjugated to polysaccharides and/or other polymers for use in a vaccine formulation. Additional substances that can be included in a product for use in the present methods include, but are not limited to one or more preservatives such as disodlum or tetrasodium salt of ethylenediaminetetracetic acid (EDTA), merthiolate, and the like.

[0154]The subject to which the vaccine is administered is preferably a companion animal, most preferably, a dog or cat.

[0155]It is preferred that the vaccine of the invention, when in a vaccine formulation, be present in unit dosage form. For purposes of this invention, an immunogenic amount, when administered comprises about 1×10⁴-1×10¹³ inactivated bacterial cells, 0.1 μg-1 mg of purified protein, or 0.1 μg-10 mg of nucleic acid. In a vaccine formulation containing multiple components, the same or lesser immunogenic amounts can usefully be employed.

[0156]Appropriate therapeutically effective doses can be determined readily by those of skill in the art based on the above immunogenic amounts, the condition being treated and the physiological characteristics of the animal. Accordingly, a vaccine preparation provides a dosage of a sterile preparation of an immunogenic amount of the active ingredient(s), where the active ingredient is at least one bacteria, protein, nucleic acid, or any combination thereof. In the presence of additional active agents, these unit dosages can be readily adjusted by those of skill in the art.

[0157]A desirable dosage regimen involves administration of at least one dose of desired vaccine composition, where the antigenic content of each fraction is as stated above. Effective doses (immunizing amounts) of the vaccines of the invention may also be extrapolated from dose-response curves derived from model test systems. The mode of administration of the vaccines of the invention can be any suitable route that delivers the vaccine to the host. These include but are not limited to oral, intradermal, intramuscular, intraperitoneal, subcutaneous, intranasal routes, and via scarification (scratching through the top layers of skin, e.g., using a bifurcated needle). However, the vaccine is preferably administered subcutaneously or by intramuscular injection. Other modes of administration can also be employed, where desired, such as intradermally, intravenously, intranasally, or intratonsillarly.

[0158]Studies have shown that, for each of the above described vaccine compositions, a primary immunization of young animals (after 8 weeks of age) is desirably initiated, with booster doses administered at 12 weeks and 16 weeks of age. Annual re-vaccination is recommended.

[0159]The vaccine of the present invention is administered and dosed in accordance with good medical practice, taking into account the clinical condition of the individual subject, the site and method of administration, scheduling of administration, subject age, sex, body weight and other factors known to medical practitioners.

[0160]The invention further provides kits for the prevention periodontal disease in companion animals. In one embodiment, the kit provides a container comprising a therapeutically effective amount of a composition which prevents periodontal disease in companion animals. Also provided in the same or different container is a pharmaceutically acceptable carrier that may be used in the composition. The kit can additionally include an adjuvant that can be used to aid in creating the response to the composition of the present invention. Also, the kit can include a dispenser for dispensing the composition, preferably in unit dosage form. The dispenser can, for example, comprise metal or plastic foil, such as a blister pack. The kit can be accompanied by a label or printed instructions describing administration of the composition to prevent periodontal disease in a companion animal. Compositions comprising a vaccine composition of the present invention formulated in a pharmaceutically acceptable carrier can also be prepared, placed in an appropriate container, and labeled for treatment of the indicated periodontal condition.

Determination of Vaccine Efficacy

[0161]The specific mechanism of protection induced by the vaccines and vaccine compositions of the present invention is the induction of the antibody and/or cellular immune response in vaccinated animals, as indicated by the in vivo animal tests described below.

[0162]The bacteria, polynucleotides, polypeptides, vaccines, and vaccine compositions of the present invention may be useful in treating or preventing companion animal periodontal disease, bovine foot rot, coronary heart disease (dogs), or systemic infections (dogs). In addition, the compositions of the present invention may also be useful in treating or preventing certain illnesses in companion animals corresponding to similar illnesses in humans such as coronary heart (or vascular or artery) disease, parotitis, oral maloder, gingivitis, periodontitis, stroke, atherosclerosis, hyperlipidemia, increased incidence of pre-term delivery of low birth weight infants, bacterial vaginosis and intrauterine growth retardation (IUGR).

[0163]In a further aspect of the present invention, methods of assessing the efficacy of a vaccine against one or more periopathogenic bacteria in an animal are provided. The present invention has shown that a vaccine against one or more periopathogenic bacteria can be assessed in animal species such as mouse or dog, particularly dog.

[0164]According to the present invention, vaccines against a variety of periopathogenic bacteria can be assessed using the methods described hereinabove, including but not limited to, Porphyromonas, Bacteriodes, Prevotella, Tannerella (Tannerella forsythensis, formerly Bacteroides forsythus), and Treponema, which are designed for treating or preventing a periodontal disease in human or companion animals caused by these bacteria. The vaccines can contain inactivated or attenuated bacteria, polypeptides, or polynucleotides of any of these bacterial species.

[0165]The efficacy of a vaccine can be assessed by introducing a challenge culture separately into a vaccinated animal and an unvaccinated animal, and comparing the clinical signs in the two animals. The challenge culture can be composed of the same periopathogenic bacteria as the vaccine. However, the challenge culture can contain bacteria different from those in the vaccine to evaluate any cross protection the vaccine may have against other bacterial species.

[0166]According to the present invention, it is desirable to introduce the challenge culture into the root canal of teeth of the animals from which the root material has been extirpated, followed by placement of a restoration. The challenge culture typically contains about 1×10² to about 1×10¹² colony forming units (CFU) per challenge dose; preferably, 1×10² to about 1×10¹¹ colony forming units (CFU) per challenge dose; even more preferably, about 5×10⁷ to about 5×10¹⁰ colony forming units (CFU) per challenge dose.

[0167]Clinical signs of disease which can be evaluated include increased levels of one or more periopathogenic bacteria in the gingival crevicular fluid, plaque, infected bone, or gingival sulci, or changes in the amount of aveolar bone, particularly in the periapical region of the aveolar bone. The bone changes can be quantitated by, e.g., radiographic measurements.

[0168]The present invention is further illustrated by the following non-limiting example and accompanying figures.

EXAMPLE 1

Companion Animal Crevicular Fluid Sample

[0169]Microbial samples were taken from dogs and cats examined at veterinary clinics for periodontal treatment, or dogs examined at either Pfizer Terre Haute or Pfizer Sandwich facilities for normal check-ups. Dogs with periodontal pockets >3 mm and cats with periodontal pockets >2 mm were included in this study. Dental indices (gingival index and periodontal index) and the periodontal pocket depths were recorded. Individual coarse absorbent paper points (Henry Schein; Melville, N.Y.) were aseptically inserted into the periodontal pocket. Upon removal, the paper points were immediately inserted into vials containing Pre-Reduced Anaerobically Sterile (PRAS) Anaerobic Dental Transport (ADT) Medium (Anaerobe Systems; Morgan Hills, Calif.).

[0170]Vials were transferred into a Bactron IV anaerobic chamber (Sheldon Manufacturing, Cornelius, Oreg.) and processed under 90% N₂, 5% H₂, 5% CO₂. The paper points were aseptically placed into 50 μl of PRAS Brain Heart Infusion (BHI) medium (Anaerobe Systems) and vortexed for 30 seconds. Dilutions of 1:100 and 1:1000 were prepared in BHI medium. Aliquots of 100 μl of the 1:100 and 1:1000 dilutions were spread on PRAS Burcella Blood Agar (BRU) plates (Anaerobe Systems). The plates were incubated at 37° C. in the anaerobic chamber for five to seven days. The total number of bacterial colonies and the number of Black Pigmented Anaerobic Bacteria (BPAB) colonies were counted. Individual BPAP colonies were transferred to new BRU plates and re-incubated as above.

Clinical Isolate Characterization

[0171]Each clinical isolate was subjected to a number of biochemical analyses and 16S rRNA DNA sequence analysis, using primers D0056 and D0057 (Seq. ID No. 1 and Seq. ID No. 2; Table 1), to determine genus and species. Individual isolates were streaked on BRU plates. Kanamycin, Vancomycin, and Colistin disks (Anaerobe Systems) were placed on the agar surface to determine the KVC resistance patterns of each isolate. Purified colonies were also subjected to the indole and catalase tests (Anaerobe Systems). Individual isolates were transferred to Egg Yolk Agar (EYA) plates (Anaerobe Systems) in order to determine lipase and lecithinase production patterns. This data is shown in Table 2.

[0172]The isolates were typed based on their 16S rRNA DNA sequence. Individual, well-isolated colonies were utilized as template for polymerase chain reactions (PCR) amplification of the 16S rRNA region using primers D0056 and D0057 (Seq. ID No. 1 and Seq. ID No. 2; Table 1) in triplicate. The PCR was carried out in 50 μl reaction volumes containing 1×PCR buffer (Life Technologies; Rockville, Md.), 1.0 mM MgCl₂, 1.25 μM each primer, 300 μM each deoxy-NTP, and 2.5 U Platinum Pfx DNA Polymerase (Life Technologies). The following PCR cycle conditions were utilized: a two minute denaturation step at 94° C.; 30 cycles of denaturation at 94° C. for 40 seconds, annealing at 60° C. for 40 seconds, and extension at 72° C. for one minute; a final extension step at 72° C. for two minutes; and a final cooling step to 4° C. A GeneAmp 9700 thermocycler (Perkin Elmer Applied Biosystems; Foster City, Calif.) was utilized for all PCR amplifications.

[0173]The resulting PCR products were purified using the PCR preps kits (Promega Corp.; Madison, Wis.) and pooled by isolate. The purified PCR products were then desalted by drop analysis against 25 ml sterile water using a 0.025 μm nitrocellulose filter (Millipore Corp.; Bedford, Mass.). The purified, desalted PCR products were subjected to DNA sequence analysis using the DyeDeoxy termination reaction on an ABI automated DNA sequencer (University of Texas Genetics Core Facility, Houston, Tex. and Lark Technologies Inc., Houston, Tex.). Synthetic oligonucleotide primers D0056, D0057, PFZ175-AP1, PFZ175-AP2, and PFZ175-AP3 (Seq. ID No. 1-5, respectively; Table 1) were used to obtain double stranded DNA sequence. The resulting DNA sequences were used to search publicly available DNA databases using A BLAST-N program publicly available from The National Center for Biotechnology Information, USA.

[0174]The bacterial isolates were typed based on the closest match identified by database searches. The B106 isolates did not have a precise match. The nearest match was with an uncultured bacterial type that was identified by random PCR of human periodontal pocket material. This isolate was referred to as Porphyromonas denticanis strain B106. A complete listing of all the isolates and their respective characteristics is located in Table 2. The top nine most frequently isolated strains are exemplified by the following isolates: P. gulae B43 (dog sample Sandwich 4), P. cansulci B46 (dog sample VHUP 1B), P. circumdentaria B52 (cat sample VHUP 2A), P. gulae B69 (cat sample VHUP 3A), P. circumdentaria B97 (dog sample TH 1bC), P. cangingivalis B98 (dog sample TH 1aC), P. salivosa B104 (dog sample TH 1 bC), P. denticanis B106 (dog sample TH 1bE), and P. endodontalis B114 (dog sample TH 2bA).

[0175]The distribution of isolates is shown in Table 3.

[0176]The isolates listed above represent those species that were most frequently identified and present in the highest percentages of dogs or cats.

[0177]The following companion animal periodontal isolates were deposited with the American Type Culture Collection (ATCC), 10801 University Blvd., Manassas, Va., 20110, USA, on Aug. 9, 2001: P. gulae B43 (PTA-3618), P. cansulci B46 (PTA-3619), P. circumdentaria B52 (PTA-3620), P. gulae B69 (PTA-3621), P. circumdentaria B97 (PTA-3622), P. cangingivalis B98 (PTA-3623), P. salivosa B104 (PTA-3624), P. denticanis B106 (PTA-3625), and P. endodontalis B114 (PTA-3626).

Culture Conditions for Porphyromonas Sp

[0178]Since the standard growth media for Porphyromonas sp. (Brain Heart Infusion (BHI) and Chopped Meat Carbohydrate (CMC) media) contain animal product, which are not amenable for vaccine production, a growth medium that does not contain these ingredients was sought. Various media compositions, with and without the addition of hemin and vitamin K, were tested for their ability to support growth equivalent to that of growth of BHI or CMC. Both the PYG-complete medium and ME-complete medium supported the growth of P. gulae B43 (PTA-3618) to a level equivalent to that of BHI (FIG. 1). The PYG-complete medium was chosen as the P. gulae B43 (PTA-3618) growth medium due to its ability to yield high density cultures during fermentation. This medium contains the following ingredients: 3% phytone (Becton Dickinson; Cockeysville, Md.), 0.3% yeast extract (Becton Dickinson), 0.3% glucose (Sigma Corp.; St. Louis, Mo.), 0.05% sodium thioglycollate (Becton Dickinson), 0.5% sodium chloride (Sigma Corp.), 5 μg/ml hemin (Sigma Corp.) (added after autoclaving), 0.5 μg/ml menadione (Sigma Corp.) (added after autoclaving), and 0.2% sodium bicarbonate (Sigma Corp.), pH 7.0.

[0179]P. gulae B43 (PTA-3618) was routinely cultivated on Brucella blood agar plates (Anaerobe Systems) or in complete PYG medium or BHI at 37° C. in a Bactron IV anaerobic chamber (Shel Labs; Cornelius, Oreg.) under 90% N₂, 5% CO₂ for three to five days (plates) or 24 to 48 hours (liquid cultures). For whole cell bacterin preparation, P. gulae B43 (PTA-3618) was cultivated in a BioFlo 3000 Bioreactor using 5 liters of PYG complete medium. The culture medium in the vessel was rendered anaerobic by sparging with 95-99.5% N₂ and 0.5-5% CO₂ immediately after autoclaving. The reduced culture medium was seeded with 0.02% of P. gulae B43 (PTA-3618) stock and cultivated at 37° C. with an agitation rate of 100 rpm and the pH maintained at 7.0 by the automatic addition of NaOH. During cultivation, the vessel was periodically sparged with both N₂ and CO₂. The bacterial cells were collected after 36 to 48 hours at an OD₆₀₀ of 2.0 to 3.5 while cells were still undergoing logarithmic growth.

Pathogenicity Testing of Clinical Isolates in Mice

[0180]The nine isolates (P. gulae B43, P. cansulci B46, P. circumdentaria B52, P. gulae B69, P. circumdentaria B97, P. cangingivalis B98, P. salivosa B104, P. denticanis B106, and P. endodontalis B114) were tested for their pathogenicity in the mouse periodontal bone loss model. Three-week-old, age-matched male Balb/c CyJ mice (Jackson Laboratories; Bar Harbor, Me.) with estimated weights of 14-15 grams were utilized for this study. The animals were housed in positive pressure, barrier cage units. Food pellets, standard for the species, and water were provided ad libitum throughout the experiment. The bedding utilized was granular Bed O'Cobbs to minimize impaction in the gingival tissues. Following receipt, all animals were acclimatized for five to seven days. To reduce competing oral flora, animals were placed on a mixture of sulfamathoxazole and trimethoprim (10 ml drinking water; approximately 2 mg and 0.4 mg/ml, respectively) for ten days followed by a five-day washout period. Serum samples were taken from each mouse tail vein bleed. The animals were infected with 0.5 ml suspension of approximately 1×10¹⁰ cfu/ml of the appropriate bacterial strain in 1% carboxymethylcellulose by gavage. Additional drops were placed in the oral cavity. This infection was repeated two more times for a total of three times (Monday, Wednesday, and Friday).

[0181]Day 1 of the experiment was defined as the Tuesday following the first infection. All animals were sacrificed on Day 2. Post-infection serum was collected, as were microbial samples. The jaws of each mouse were defleshed, stained, and scored for horizontal bone loss microscopically. The scoring was repeated three times to reduce operator error. The average bone loss is expressed as the average bone loss/site/jaw in mm. Statistical analysis of the resulting data was done with Systat (version 9), SigmaStat (version 2), and SigmaPlot (version 2000) available from SPSS Science Inc. (Chicago, Ill.). Table 4 shows the numerical results for the top nine isolates.

[0182]Each of these yielded statistically significant bone loss in this model.

The mean alveolar bone levels (cementoenamel junction--alveolar bone crest) were obtained at 14 maxillary sites in mm, and the mean value for each jaw was determined. For each experimental group, the mean values for each jaw were summed and the group mean derived by dividing by the total number of animals in that group.

[0184]FIG. 3 graphically shows the comparison of net bone loss. The mean alveolar bone levels (cementoenamel junctions--alveolar bone crest) were obtained at 14 maxillary sites in mm, and the mean value for each jaw was determined. For each experimental group, the mean values for each jaw were summed and the group mean derived by dividing by the total number of animals in that group. The net bone loss was determined by subtracting the sham infected mean values from each experimental groups. The data is presented as a percentage of the positive control group (P. gingivalis 53977) which is set at 100%. P. gingivalis W50 is a poorly fimbrinated strain that has reduced virulence in this animal model.

[0185]These data indicate that the following clinical isolates are capable of producing high levels of bone loss in the mouse model of periodontal disease: P. gulae B43 (PTA-3618), P. gulae B69 (PTA-3621), P. cangingivalis B98 (PTA-3623) and P. denticanis B106 (PTA-3625). The following clinical isolates yielded moderate bone loss in the mouse periodontal model: P. cansulci B46 (PTA-3619), P. salivosa B104 (PTA-3624), and P. endodontalis B114 (PTA-3626). The following clinical isolates yielded minimal bone loss in the mouse periodontal model: P. circumdentaria B52 (PTA-3620) and P. circumdentaria B97 (PTA-3622). While varying amounts of bone loss were observed between the clinical isolates, it should be noted that in each case, the amount of bone loss observed was well above what was observed in the sham infected mice. Based on these data, it can be concluded that each of the top nine clinical isolates is capable of causing periodontal disease either alone or in concert with other bacteria.

Preparation of Bacterial Cells and Genomic DNA

[0186]Porphyromonas spp. were anaerobically cultivated in BHI or complete PYG at 37° C. for 48 hours. Cells from a 1-3 ml culture were pelleted by centrifugation, washed once in an equal volume of anaerobic PBS, re-centrifuged, and re-suspended in 1/10 volume anaerobic PBS.

[0187]Genomic DNA was purified from 5 ml cultures of Porphyromonas spp. that were anaerobically cultivated in BHI or complete PYG at 37° C. for 48 hours. The Wizard Genomic DNA Extraction kit (Promega Corp.) was utilized for all genomic DNA preparations.

Cloning of the Fimbrial Gene from Clinical Isolates

[0188]The fimA gene was PCR amplified from genomic DNA isolated from the top ten clinical isolates using combinations of the following PCR primers D0067 (forward; Seq. ID No. 6), D0078 (forward; Seq. ID No. 8), D0097 (forward; Seq. ID No. 9), D0068 (reverse; Seq. ID No. 7) and D0098 (reverse; Seq. ID No. 10). The PCR was carried out in 50 ul reaction volumes containing 1×PCR buffer (Life Technologies), 1.0 mM MgCl₂, 1.25 μM each primer, 300 M each deoxy-NTP, and 2.5 U Platinum Pfx DNA Polymerase (Life Technologies). The following PCR cycle conditions were utilized: a two minute denaturation step at 94° C.; 30 cycles of denaturation at 94° C. for 40 seconds, annealing at 60° C. for 40 seconds, and extension at 72° C. for 1.5 minutes; a final extension step at 72° C. for five minutes; and a final cooling step to 4° C. A GeneAmp 9700 thermocycler (Perkin Elmer Applied Biosystems; Foster City, Calif.) was utilized for all PCR amplifications. The amplified products were visualized on a 1.2% E-gel (Invitrogen; Carlsbad, Calif.).

[0189]The PCR products were A-tailed using 10 units of KlenTaq polymerase (Ab Peptides, Inc.; St. Louis, Mo.) for five minutes at 72° C. The resultant products were immediately T-tail cloned into the pCR2.1-TOPO vector (Invitrogen) using the manufacturer's protocol and transformed into E. coli Top10F' (Novagen; Madison, Wis.). Transformants harboring recombinant plasmids with the correct insert DNA were identified by a combination of colony PCR, restriction enzyme digestion, and DNA sequence analysis using DyeDeoxy termination reactions on an ABI automated DNA sequence (Lark Technologies, Inc.). Synthetic oligonucleotide primers (Seq. ID No. 6, 7, 8, 11-42) were used to obtain double stranded DNA sequence.

Cloning of the P. gulae B43 FIMA Gene into Expression Plasmids

[0190]For the purpose of high-level protein expression, the P. gulae B43 (PTA-3618) fimA gene was cloned into the pBAD/HisA expression vector (Invitrogen). Genomic DNA was purified from a 5 ml culture of P. gulae B43 in BHI incubated at 3700 for two days anaerobically using the genomic DNA extraction kit (Promega Corp.). The fimA gene was PCR amplified using primers D0097 and D0098 (Seq. ID No. 9 and Seq. ID No. 10) in triplicate. The PCR was carried out in 50 ul reaction volumes containing 1×PCR buffer (Life Technologies), 50 ng P. gulae B43 genomic DNA, 1.0 mM MgCL₂, 1.25 μM each primer, 300 μM each deoxy-NTP, and 2.5 U Platinum Pfx DNA Polymerase (Life Technologies, USA).

[0191]The following PCR cycle conditions were utilized: a two minute denaturation step at 94° C.; five cycles of denaturation at 94° C. for 40 seconds, annealing at 58° C. for 40 seconds, and extension at 72° C. for 1.5 minutes; 30 cycles of denaturation at 94° C. for 40 seconds, annealing at 65° C. for 40 seconds, and extension at 72° C. for 1.5 minutes; a final extension step at 72° C. for five minutes; and a final cooling step to 4° C. A GeneAmp 9700 thermocycler (Perkin Elmer Applied Biosystems) was utilized for all PCR amplifications. The PCR products were purified using PCR prep kits (Promega Corp.). The purified PCR products and pBAD/HisA were double digested with HindIII and XhoI for three hours at 37° C. Half way through the digestion, five units of shrimp alkaline phosphatase (SAP) (Amersham Pharmacia Biotech, Inc.: Piscataway, N.J.) were added to the vector digestion. The digested DNA's were purified using the DNA Clean-Up kit (Promega Corp.). The purified HindIII/XhoI digested PCR products were ligated into HindIII/XhoI digested, SAP treated pBAD/HisA with the T4 DNA Ligase enzyme (Life Technologies) in the presence of 1×T4 DNA ligase buffer at 16° C. for 18 hours. A portion of the resulting ligation mixture was transformed into competent E. coli Top10F' cells (Novagen). A recombinant plasmid, pBAD:B43fimA4, was found to contain the fimA gene in the correct orientation. The resulting recombinant FimA contains a terminal, vector-encoded sequence

[0192](MGGSHHHHHHGMASMTGGQMGRDLYDDDDKDRWGSELEICSQYHMGI, SEQ ID NO: 135), followed by the mature portion of FimA beginning at asparagine-20. This plasmid was transformed into competent E. coli BL21 cells (Novagen) for further protein expression analysis.

Expression and Purification of the Recombinant FIMA Protein

[0193]A frozen working stock of the E. coli BL21/pBAD:B43fimA4 was thawed, seeded at a 1:5000 dilution into Luria broth containing 100 μg/ml ampicillin (1% tryptone, 0.5% yeast extract, 0.5% NaCl), and grown in a 5 liter working volume BioFlo 3000 Bioreactor (New Brunswick Scientific; Edison, N.J.) at 37° C. with a 100 rpm agitation rate until A₆₂₅ was 2.5-3.5. L-arabinose was then added to the culture at a final concentration of 0.1% to induce FimA expression. The culture was incubated for an additional three hours. Expression of the recombinant FimA was detected by SDS-PAGE and Western blot analysis using anti-Express serum (Invitrogen) (FIG. 4). The recombinant FimA protein had a predicted molecular mass of 45 kDa.

[0194]Wet cells of the E. coli BL21 transformant expressing recombinant FimA from the 5 liter fermentation were harvested by centrifugation and re-suspended in phosphate-buffered saline. The cells were mechanically lysed. Following centrifugation, the pellet was discarded. The supernatant was passed over a Ni²+-affinity column, and eluted off using an imidazole gradient. Fractions containing the recombinant protein were pooled, dialyzed to remove the imidazole, and filter-sterilized using a 0.2 μm filter.

Cloning of the OPRF Gene from Clinical Isolates

[0195]Based on sequences of the P. gingivalis strain W50 oprF homolog, gene PG32 (Genbank accession number AF175714), oligonucleotide primers D0086 (SEQ ID No. 43), D0087 (SEQ ID NO. 44), and KWK-Pg-03 (SEQ ID NO. 45) were designed and synthesized (Life Technologies). For PCR, primer D0086 (SEQ ID NO. 43) was used in conjunction with either D0087 (SEQ ID NO. 44) or KWK-Pg-03 (SEQ ID NO. 45) in 1×PC2 buffer (Ab Peptides), 200 μM each dNTP, 7.5 U KlenTaq1 (Ab Peptides) and 0.15 U cloned Pfu (Stratagene; La Jolla, Calif.) thermostable polymerases in a 50111 final sample volume. Reactions were performed in triplicate using either a washed cell suspension or purified genomic DNA as template from P. gulae B43, P. cansulci B46, P. circumdentaria B52, P. gulae B69, P. circumdentaria B97, P. cangingivalis B98, P. salivosa B104, P. denticanis B106, and P. endodontalis B114. Amplification was carried out as follows: denaturation (94° C., 9 minutes); 30-40 cycles of denaturation (94° C., 30 seconds), annealing (55-60° C., 30 seconds), and polymerization (72° C., 1.5 minutes); followed by a final extension at 72° C. for seven minutes.

[0196]For polymerase chain amplification of the oprF homolog from P. cangingivalis B98, primer KWK-Ps-04b (SEQ ID No. 81) was used in conjunction with KWK-Ps-06b (SEQ ID No. 83). For amplification of the homolog from P. salivosa B104, primer KWK-Ps-04b (SEQ ID No. 81) was used with KWK-Ps-05b (SEQ ID No. 82). For amplification of the gene from P. denticanis B106, primer KWK-Ps-02 (SEQ ID No. 79) was used with KWK-Ps-03 (SEQ ID No. 80). Reactions were performed in triplicate using purified chromosomal DNA as template from strains P. cangingivalis B98, P. salivosa B104, and P. denticanis B106. Amplification was carried out as follows: denaturation (94° C., 9 minutes); 30-35 cycles of denaturation (94° C., 30 seconds), annealing (61-72° C., 30 seconds), and polymerization (72° C., 1.5 minutes); this was followed by a final extension at 72° C. for 7 minutes.

[0197]The PCR amplified gene products were visualized by separation on a 1.0% agarose gel (Sigma). The PCR products were purified using a QIAquick® PCR Purification kit (Qiagen; Valancia, Calif.), and each set of triplicate samples pooled. These fragments were then sequenced directly in an attempt to avoid the introduction of sequence artifacts due to mutations that arise during PCR amplification and subsequent cloning steps. The pooled mixtures were then subjected to direct sequence analysis using DyeDeoxy termination reaction on an ABI automated DNA sequencer (Lark Technologies). Synthetic oligonucleotide primers (SEQ ID NO. 46-75) were used to sequence both DNA strands of the amplified products.

[0198]The nucleotide sequences encoding the OprF homolog from P. gulae B43, P. cansulci B46, P. circumdentaria B52, P. gulae B69, P. circumdentaria B97, P. cangingivalis B98, P. salivosa B104, P. denticanis B106, P. cangingivalis B98, P. salivosa B104, P. denticanis B106, and P. endontalis B114 are depicted in SEQ ID NO. 111 to 119. Sequence corresponding the 5' and 3' primers used for PCR amplification of each gene was removed, as it may not represent the actual sequence of the gene in each of the respective strains. The ORFs encoded by SEQ ID NO. 111 to 119 are shown in SEQ ID No. 120 to 128, respectively. For each of the encoded ORFs, the amino terminal sequence, even when that encoded by the 5' primer was excluded, still maintained characteristics of a prokaryotic signal sequence (von Heijne, 1985, J. Mol. Biol. 184:99-105; Nielsen, H., Engelbrecht, J., Brunak, S., and von Heijne, G., 1997 Protein Engineering, 10:1-6). Each ORF was compared against existing nucleotide and protein databases using the Basis Local Align Search Tool (BLAST) programs (Altschul, S. F., Gish, W., Miller, W., Myers, E. W., Lipman, D. J., 1990, J. Mol. Biol. 215:403-410). The entry with which each shared the greatest homology was PG32 from P. gingivalis.

Cloning of the P. gulae B43 OPRF Gene into Expression Plasmids

[0199]For the purpose of recombinant protein expression, the gene encoding OprF was cloned with the sequence encoding its signal peptide. OprF was amplified from P. gulae B43 using oligonucleotide primers KWK-Pg-06 (SEQ ID NO. 76) and KWK-Pg-03 (SEQ ID NO. 45). For polymerase chain amplification, duplicate 50 μl reactions were set up containing chromosomal DNA as template, 1×PC2 buffer, 200 μM each dNTP, 50 pMol each primer, 7.5 U KlenTaq1 and 0.15 cloned Pfu thermostable polymerase. Amplification was carried out as follows: denaturation (94° C., nine minutes); 30 cycles of denaturation (94° C., 30 sec), annealing (60° C., 30 sec), and polymerization (72° C., 1.5 min), followed by a final extension at 72° C. for 7 minutes. Following amplification, the samples were purified (QIAquick® PCR Purification kit) and pooled, The purified PCR product was cloned directly into the TA cloning site of both pBAD-TOPO and pBAD/Thio-TOPO (Invitrogen). The ligand products were transformed into Max Efficiency E. Coli DH5a cells. The predicted amino terminal sequence of the encoded protein expressed from pBAD-TOPO:OprF consists of the vector-encoded sequence MGSGSGDDDDKLALM (SEQ ID NO: 136) followed immediately by the sequence beginning at glutamine-13 of OprF (SEQ ID No. 120). A clone containing the appropriate plasmid was identified, and purified plasmid was isolated from a small-scale broth culture using a QIAprep Spin Miniprep kit (Qiagen). This plasmid was transformed into E. coli BL21 cells (Novagen), and a clone was identified that contained the appropriate plasmid.

[0200]The predicted amino terminal sequence of the encoded fusion protein expressed from pBAD/Thio-TOPO: oprF should consist of the thioredoxin protein and a 14 amino acid residue linker followed immediately by the sequence beginning at glutamine-13 of OprF (SEQ ID NO. 120). A clone containing the appropriate plasmid was identified, and purified plasmid was isolated from a small-scale broth culture using a QIAprep Spin Miniprep kit. This plasmid was transformed into E. coli BL21 cells, and a clone was identified that contained the appropriate plasmid.

[0201]The oprF gene lacking the sequence encoding the signal peptide was also cloned into two different λ expression plasmids. Both of these plasmids encode the temperature-sensitive λ repressor c/857, which inhibits expression from λ promoters at 30° C. At 42° C., the repressor is inactivated and expression from the λ promoter is enabled, yielding high-level transcription and translation. For cloning into these vectors, oprF was amplified from P. gulae B43 using oligonucleotide primers KWK-Pgu-14 (SEQ ID NO. 77) and KWK-Pgu-15 (SEQ ID NO. 78). For polymerase chain amplification, duplicate 50 μl reactions were set up containing washed P. gulae B43 cells as template, 1×PC2 buffer, 200 μM each dNTP, 50 pMol each primer, 7.5 U KlenTaq1 and 0.15 U cloned Pfu thermostable polymerases. Amplification was carried out as follows: denaturation (94° C., nine minutes); 45 cycles of denaturation (94° C., 30 seconds), annealing (55° C., 30 seconds), and polymerization (72° C., 1.5 minutes), followed by a final extension at 72° C. for seven minutes. Following amplification, the samples were pooled and digested with restriction enzymes, generating overhangs compatible with the plasmids which had also been linearized using the same enzymes. Following restriction digestion, the PCR fragment and plasmids were purified (QIAquick® PCR Purification kit; Qiagen Corp.), ligated, and transformed into E. coli DH5α cells (Novagen). The predicted amino terminal consisted of the vector-encoded sequence MGTTTTTTSLHM (SEQ ID NO: 137) followed immediately by the sequence beginning at Glutamine-13 of OprF (SEQ ID NO. 120). The protein expressed from the second plasmid would consist only a vector-encoded Met followed by Glutamine-13 of OprF (SEQ ID NO: 120). Clones containing the appropriate plasmids were identified, and plasmids were isolated from small-scale broth cultures using QIAprep Spin Miniprep kits (Qiagen Corp.). These plasmids were transformed into E. coli BL21 cells, and separate clones were identified that contained the appropriate plasmids.

Expression and Purification of the Recombinant OPRF Protein

[0202]E. coli BL21 cells that express recombinant OprF (fused at its N-terminus to SEQ ID NO: 137) were utilized for expression studies. A frozen stock was thawed, seeded at a 1:5000 dilution into 2×YT medium containing 50 μg/ml kanamycin sulfate (1.6% tryptone, 1% yeast extract, 0.5 NaCL), and grown in a 5 liter working volume BioFlo 3000 Bioreactor (New Brunswick Scientific; Edison, N.J.) at 29° C. with a 100 rpm agitation rate until A₆₂₅ was 2.5-3.5. The cultures were then shifted to 42° C. to induce OprF expression. The culture was incubated for an additional 3 hours. Aliquots were removed at various time points, centrifuged, and re-suspended in reducing sample buffer. All samples were analyzed on a 10% NuPAGE gel (Invitrogen, USA) (FIG. 5).

[0203]Wet cells of the E. coli BL21 transformant expressing recombinant OprF from the 5 liter fermentation were harvested by centrifugation and re-suspended in phosphate-buffered saline. The cells were mechanically lysed. Following centrifugation, the pellet was discarded. The supernatant was passed over an ion exchange column, and eluted off using a NaCl gradient. Fractions containing the recombinant protein were pooled, dialyzed to remove the NaCl, and filter-sterilized using a 0.2 μm filter.

Whole Cell Bacterin Preparation

[0204]A 5 liter batch of P. gulae B43 was grown in a fermentor as described above and split into 1 liter portions. The cells in each 1 liter fraction (4.4×10¹² total P. gulae B43 cells) were inactivated by the following treatments: exposure to 0.4% formalin for 24 hours at 23° C., exposure to 10 mM binary ethylene-imine (BEI) at pH 8.5 for 48 hours at 37° C., heating to 60° C. for 30 minutes on two consecutive days, and exposure to air for 48 hours. Following the BEI treatment, the BEI was inactivated by treatment with 50 mM sodium thiosulfate. The cells were collected by centrifugation. The resultant cells pellets were re-suspended in 220 ml PBS yielding a final concentration of 2×10¹⁰ cells per ml. Seven ml of each of the inactivated cells was mixed with 7 ml of MPL+TDM adjuvant (Sigma Corp.) yielding a final concentration of 1.0×10¹⁰ cells per ml.

[0205]Whole cell bacterin preparations of the other eight top clinical isolates (P. cansulci B46, P. circumdentaria B52, P. gulae B69, P. circumdentaria B97, P. cangingivalis B98, P. salivosa B104, P. denticanis B106, and P. endodontalis B114) or other pigmented anaerobic bacteria can be prepared in an identical fashion.

Homologous Vaccine Efficacy in Mice

[0206]In homologous vaccine efficacy studies, mice were immunized with two injections of 0.2 ml each of the above mentioned inactivated P. gulae B43 cells in MPL+TDM adjuvant three weeks apart. The mice were infected as previously described with P. gulae B43 two weeks following the booster immunization. Forty-two days following the infection, the mice were sacrificed and processed as previously described. Table 5 shows the numerical results of bone loss measurements.

(b) Percentage calculated based on group C as the positive control group. (c) NA = Not applicable.

[0207]FIGS. 6, 7, and 8 graphically display these results. FIG. 7 shows the percent bone loss for the control experiment. Vaccines containing formalin-inactivated P. gingivalis 53977 and either Freund's complete/incomplete or MPL+TDM adjuvants reduced the bone loss induced by infection with P. gingivalis 53977 by approximately 32% and 43%, respectively. FIG. 8 shows the percent bone loss for the test experiment. Vaccines containing either formalin-, heat-, or air-inactivated P. gulae B43 and MPL+TDM adjuvant reduced the bone loss induced by infection with P. gulae B43 by approximately 45%, 35%, and 75%, respectively. Based on these data, it can be concluded that the formalin-, air-, and heat-inactivated P. gulae B43 vaccines were efficacious in their ability to reduce bone loss induced in this superinfection model. Extrapolating this data into the clinical setting, these three vaccines would likely be efficacious in the prophylactic prevention of periodontal disease and may well prove efficacious in the therapeutic treatment of periodontal disease.

Heterologous Vaccine Efficacy Study in Mice

[0208]In heterologous vaccine efficacy studies, mice were immunized with two injections of 0.2 ml each of either formalin-inactivated P. gulae 643 or formalin-inactivated P. salivosa B104 and P. denticanis B106 cells in MPL+TDM adjuvant three weeks apart. The mice were infected as previously described with either P. gulae B43, P. gulae B69, P. salivosa B104, or P. denticanis B106 two weeks following the booster immunization. Forty-two days following the infection, the mice were sacrificed and processed as previously described. Table 6 shows the numerical results of bone loss measurements.

[0209]FIGS. 9, 10, 11, 12, and 13 graphically display these results. FIG. 9 shows the net bone loss for these experiments. FIG. 10 shows the percent bone loss for the P. gulae B43 infected groups. Formalin-inactivated P. gulae B43 and MPL+TDM adjuvant reduced the bone loss induced by infection with P. gulae B43 by approximately 84%. FIG. 11 shows the percent bone loss for the P. gulae B69 infected groups. The formalin-inactivated P. gulae B43 and formalin-inactivated P. salivosa B104/P. denticanis B106 vaccines containing MPL+TDM adjuvant reduced the bone loss induced by infection with P. gulae B69 by approximately 40% and 49%, respectively. FIG. 12 shows the percent bone loss for the P. salivosa B104 infected groups. Formalin-inactivated P. gulae B43 and MPL+TDM adjuvant reduced the bone loss induced by P. salivosa B104 by approximately 65%. FIG. 13 shows the percent bone loss for the P. denticanis B106 infected groups. Formalin-inactivated P. gulae B43 with MPL+TDM adjuvant failed to cross protect against challenge with P. denticanis B106. Based on these data, it can be concluded that the formalin-inactivated P. gulae B43 vaccine adjuvanted with MPL+TDM was capable of providing protection not only from homologous challenge, but also from heterologous challenge with P. gulae B69. Moreover, protection was observed between two Porphyromonas species as the P. gulae B43 vaccine protected against P. salivosa B104 challenge. Extrapolating this data into the clinical setting, a multi-valent vaccine would likely be efficacious in the prophylactic prevention of periodontal disease and may well prove efficacious in the therapeutic treatment of periodontal disease.

Recombinant FimA and OprF Mouse Serological Study

[0210]In subunit vaccine serology studies, mice were immunized with two injections of 0.2 ml each of either recombinantly expressed, purified P. gulae B43 FimA or recombinantly expressed, purified P. gulae B43 OprF in QuilA/Cholesterol adjuvant three weeks apart. The mice were bled prior to the first vaccination and two weeks following the booster immunization. Table 7 shows the numerical results while FIGS. 14 and 15 show the results graphically.

[0212]Ten beagle dogs with adult dentition were used for this study. The animals were anesthetized, and an access was made to the root canal of the mandibular premolars and first molars using a pear-shaped dental burr (Midwest Dental Products Corp; Des Plaines, Ill.) in a Schein Ultima 2000 dental unit with a high-speed handpiece (Henry Schein Inc.; Melville, N.Y.). Access to the root canal was confirmed by passing a veterinary barbed broach (21 mm, size #5; Roydent Dental Products; Johnson City, Tenn.) into the canal to a depth approximating the depth of the root canal. The connective tissue, vessels and nervous tissue were removed using repeated passages of the barbed broach. Hemorrhaging was minor; hemostasis was achieved with sterile paper points (Henry Schein Inc.) placed in the canal. It was important at this point to ensure that any inadvertent contamination of the canal during the drilling and emptying of the canal was removed. Therefore the canal was flushed with a 10% bleach solution. To create an appropriate surface for placement of the restoration, the enamel surrounding the access port was etched using a 40% sulfuric acid gel (Scotchbond Etching Gel, 3M; St. Paul, Minn.). In order to prevent any impact on viability of the challenge material by residual bleach solution or acid gel, the root canal was flushed from the inside out, using an endodontic needle (27ga., Dentsply Pharmaceutical; York, Pa.) and copious amounts of sterile saline. The access area and canal were dried with sterile paper points.

[0213]The challenge material was prepared by growing Porphyromonas gulae strain B69 on Brucella blood agar (Anaerobe Systems; Morgan Hill, Calif.), and incubating at 37° C. in an anaerobic environment (5% H₂, 5% CO₂, 90% N₂). Cells were harvested and resuspended in sterile SSYG media. A challenge dose of approximately 7.5×10⁸ colony forming units (CFU) was then introduced into the exposed root canal cavity of the selected teeth with an endodontic needle. Five animals received the challenge material (T01), while the other five received a sham challenge consisting of sterile SSYG media (T02). The access port was then sealed with a combination of glass ionomer and light-cured dental composite restorative (Revolution 3; 3M).

[0214]Periopathogenicity of the challenge organisms was determined based on changes in the density of periodontal bone surrounding the teeth. This assessment was made by measuring pixel intensities of digital radiographs taken using Schick Computed Dental Radiography (CDR®) sensors and software at study weeks 0, 3, 6, 9 and 12. Radiographs of six to eight teeth were taken in each animal. In order to obtain baseline values, radiographs were taken immediately prior to the procedure. Following challenge, radiographs were taken every three weeks for twelve weeks post-challenge. Radiographs were analyzed via two different methods. The first consisted of a subjective assessment of the radiographs by a veterinarian trained in the analysis of dental radiographs. Briefly, this consisted of a trained observer examining the radiographs, noting abnormalities and marking the degree of abnormality for each dog on a Visual Analog Scale. Secondly, areas of affected bone evident in radiographs taken 0, 6 and 12 weeks following challenge were measured using an area measurement tool within the radiograph software. This consisted of demarcating the rough diameter of visible lesions on the radiograph using the Straight-line measurement tool within Schick CDR software. From the resulting distance, the approximate area of lesion was determined. These areas were totaled for each dog and tabulated.

[0215]Analysis of radiographs using both methods suggested that the T01 group lost more periodontal bone than the T02 group (FIG. 16). It was concluded from this study that a feasible challenge model had been developed. However, because of difficulties in quantitating changes that occurred in a three-dimensional area (periodontal bone) based on two-dimensional measurements (radiographs), improved quantitation methods would be pursued.

EXAMPLE 3

[0216]Following model development, a study was conducted in dogs to test the efficacy of a trivalent vaccine preparation. The trivalent bacterin contained formalin-inactivated Porphyromonas gulae (B43), Porphyromonas salivosa (B104), and Wernerella denticanis (B106), adjuvanted with Quil A and cholesterol at 50 μg of each per dose. Each bacterin strain was assembled at an approximate concentration of 1×10¹⁰ CFU/vaccine dose. Three groups of eight animals with adult dentition were used in this study. Dogs in the first group (T01) were vaccinated intramuscularly (IM) with 1 ml of the trivalent vaccine. The second (T02) and third (T03) groups were sham vaccinated with 1 ml of sterile saline. All dogs received three intramuscularly (IM) administrations, with a three week interval between administrations. Three weeks following the final administration, animals were anaesthetized as described above, and the challenge material was introduced into the root canal of the mandibular premolars and first molars following extirpation of the root material. Dogs in the T01 and T02 groups were challenged with 1×10¹⁰ CFU of a heterologous P. gulae strain (B69), prepared as described in Example 1. Dogs in the T03 group were challenged with sterile media, in an effort to measure effects of the procedure.

[0217]Radiographs were taken using a Heliodont dental radiograph machine, Schick® CDR (computerized digital radiography) capture system, and standard techniques at three, six, nine, and twelve weeks following challenge. For this study, once the digital radiographs were obtained, sequential images from each dog were first registered against each other through ImageJ (v1.28, NIH; Bethesda, Md.), using the plug-in TurboReg® with a scaled rotation technique. Registered image sets were then calibrated using an external gray scale with a 3^rd-degree polynomial function. The area of bone surrounding treated teeth, excluding teeth and air, was then outlined and the mean density of that area was recorded for each image. Thus, a number representing the "whiteness" of the bone surrounding the tooth roots was derived objectively and made available for analysis. This number was termed the "bone reactivity score" and is a representation of the mean bone density.

[0218]The results from this study are shown in FIG. 17. The mean bone scores for animals in group T02 decreased, or became whiter, following challenge until week 12 post-challenge, when they returned to pre-challenge levels. Mean bone reactivity scores in group T01 and T03 also decreased initially, then appeared to recover to near normal values until week 12 post-challenge, when they diverged. The procedural controls in group T03 became whiter, while the vaccinated animals in group T01 maintained a mean value similar to pre-challenge levels. Thus, dogs that received the vaccine were able to recover bone density more quickly than unvaccinated dogs in the face of an endodontic challenge. Additionally, analysis of serum collected at each of the observation points indicated that animals which received vaccine generated high antibody titers against the vaccine strains and had increased antibody cross-reactivity against the challenge strain (data not shown).

[0219]The radiographs became whiter following challenge, as opposed to darker, the more intuitive direction in the case of bone infections. Bone reacts to inflammation and infection in a dual fashion, both losing bone matrix as well as increasing surrounding bone to "wall off" the spreading infection. The mixed lytic-sclerotic lesions are typical of those seen with several bone infections, but are influenced by 1) the virulence of the pathogen, 2) the age of the animal, 3) the genetics of the animal, and 4) the amount of trauma associated with the instigation of inflammation. The animals used in this study were young (10-14 months old), and there was significant trauma to the tooth and surrounding bone associated with the challenge procedure. These factors, when taken into account together with what is known regarding how bone reacts to infection and inflammation, may explain why there was an increase in the density of the surrounding bone.

EXAMPLE 4

[0220]This vaccine efficacy study was similar in design to that described in Example 3. Each treatment group contained ten animals. Dogs in the T01 group were vaccinated and challenged; the T02 group received a sham vaccination prior to challenge, and the T03 group was sham vaccinated and sham challenged. Each vaccine contained formalin-inactivated P. gulae strain B43, P. salivosa strain B104, and W. denticanis strain B106, at a concentration of 1×10⁷ CFU of each strain per dose. The vaccination schedule was identical to that set forth in Example 3. The challenge inoculum was P. gulae strain B69, administered 3 weeks following the third vaccination. Radiographs were again taken at 3 week intervals, but only until nine weeks post-challenge, and were analyzed in a similar manner as described in Example 2. FIG. 18 indicates the results of the bone reactivity analysis.

[0221]In this study, the animals reacted to the challenge procedure with increased mean bone reactivity scores. This means that the radiographs became darker, corresponding to a decrease in bone density (FIG. 19). While the radiographs indicated significant lesions in both the T01 and T02 groups, the bone in the non-vaccinated animals was much less dense overall than the bone in the vaccinates. At nine weeks, mean bone reactivity scores of the non-vaccinated dogs in group T02 were significantly different than the vaccinated group T01 (p=0.05). The dogs in this study were uniformly older than those in Example 2, and the skill of the operator had greatly improved. It is postulated that these factors contributed to reactions that were more typical of those associated with bone infections, that is, a decrease in bone density. Thus, the endodontic model of canine periodontitis is a novel and useful tool for studying periodontitis. Not only is it of value in vaccination/challenge studies associated with vaccine evaluation, but it could also be employed in antimicrobial and topical therapy studies.

EXAMPLE 5

[0222]An evaluation of systemic and local tissue reactions to the trivalent vaccine in combination with other vaccines administered to dogs was undertaken. Two groups of 5 dogs, approximately 6 weeks of age at the initiation of the study, were vaccinated IM at 6, 9 and 12 weeks of age. Blood samples were collected prior to each vaccination. All dogs were examined daily for systemic and local reactions for 1 week following each vaccination. Body temperatures were determined and recorded on these days as well. Group T01 was vaccinated with a combination of the trivalent bacterin (prepared as described in Examples 3 and 4) at a concentration of 3×10⁸ CFU of total antigen and adjuvanted with Quil A and cholesterol at 50 μg of each per dose, and the following modified live and killed viral components: Canine Distemper Virus (CDV), Canine Adenovirus-2 (CAV-2), Canine Parvovirus (CPV), Canine Parainfluenza Virus (CPI), and Canine Coronavirus (CCV). Group T02 received the trivalent bacterin at a concentration of 3×10⁶ CFU and the same combination of viral components. The results in FIG. 20 illustrate that the trivalent vaccine, when added to a combination of viral components typically administered to puppies, did not cause adverse systemic or local reactions in the test groups.
