Biology and taxonomy of Bacillus cereus, Bacillus anthracis, and Bacillus thuringiensis.
Three species of the Bacillus cereus group (Bacillus cereus, Bacillus anthracis, and Bacillus thuringiensis) have a marked impact on human activity. Bacillus cereus and B. anthracis are important pathogens of mammals, including humans, and B. thuringiensis is extensively used in the biological control of insects. The microbiological, biochemical, and genetic characteristics of these three species are reviewed, together with a discussion of several genomic studies conducted on strains of B. cereus group. Using bacterial systematic concepts, we speculate that to understand the taxonomic relationship within this group of bacteria, special attention should be devoted also to the ecology and the population genetics of these species.
