csaB gene analysis clustered 198 strains of Bacillus anthracis, Bacillus cereus, and Bacillus thuringiensis into two groups related to mammalian and insect hosts, respectively. Mammal-related group I strains also have more S-layer homology (SLH) protein genes than group II strains. This indicates that csaB-based differentiation reflects selective pressure from animal hosts.
