The pIcR regulon is involved in the opportunistic properties of Bacillus thuringiensis and Bacillus cereus in mice and insects

Article Abstract:

Results show that pIcR gene involved in encoding pleiotropic regulator of extracellular factors, controls pathogenicity of Bacillus thuringiensis and B. cereus as shown in an insect strain and mice. Data further indicate that bacterial spores also contribute to the overall entomopathogenicity.

A general strategy for identification of S-layer genes in the Bacillus cereus group: molecular characterization of such a gene in bacillus thuringiensis subsp. galleriae NRRL 4045

Article Abstract:

A strategy for identifying S-layer genes in the Bacillus cereus group is discussed. Components of S-layers of Bac. anthracis and Bac. thuringiensis are likely similar in anchoring structures, and a DNA fragment encoding the cell wall-anchoring domain of an S-layer component of the Bac. thuringiensis subsp. has been isolated and the complete gene sequenced.

Diversity and differential distribution of IS231, IS232 and IS240 among Bacillus cereus, Bacillus thuringiensis and Bacillus mycoides

Article Abstract:

Genetic research shows that the transposable insertion sequence IS231 found in organism Bacillus thuringiensis is also found it bacteria Bacillus cereus and Bacillus mycoides. However, the insertion sequence IS232 occurs only in B. thuringiensis. The transposable insertion sequence IS240 is found in all three bacteria. Primers and PCR amplification techniques were used.
