Article Abstract:
Comparison between cellulase degrading and xylanase degrading activities of several Fibrobacter succinogenes strains originating from different ruminants was conducted for assessing the validity of the model based on S85 type strain of Fibrobacter succinogenes, which is used for studying the fibrolytic properties of the species. Results indicate that F. succinogenes strains could be considered as a homologous group in terms of phylogeny and proves the validity of the model based on S85 type strain of F. succinogenes strains.

Article Abstract:
The sweet potato disease- causing strains of Streptomyces ipomoea are not related to other plant pathogens like Streptomyces scabies and Streptomyces acidiscabies. Their pathogenicity differs due to the specificity of the former to sweet potato whereas the latter infects also other crops. DNA relatedness exist among strains of the same specie regardless of geographical origin. Strains from different locations in Japan and the United States show DNA relatedness as shown by spectrophotometric analysis in this study.

Article Abstract:
Research analysis of the Acanthamoeba isolates from keratitis, non-keratitis, and asymptomatic individuals shows that clinically relevant isolates exhibit group II morphology and T4 type sequences. Pathogenicity data correlated well with the phylogenetic relationship among the samples tested.
