Identification of a Bacillus anthracis specific indel in the yeaC gene and development of a rapid pyrosequencing assay for distinguishing B. anthracis from the B. cereus group

Bacillus anthracis, the causative agent of anthrax, is a potential source of bioterrorism. The existing assays for its identification lack specificity due to the close genetic relationship it exhibits to other members of the B. cereus group. Our comparative analyses of protein sequences from Bacillus species have identified a 24 amino acid deletion in a conserved region of the YeaC protein that is uniquely present in B. anthracis. PCR primers …
