The Bacillus anthracis chromosome contains four conserved, excision-proficient, putative prophages.

Background: Bacillus anthracis is considered to be a recently emerged clone within the Bacillus cereus sensu lato group. The B. anthracis genome sequence contains four putative lambdoid prophages.

Identification of anthrax toxin genes in a Bacillus cereus associated with an illness resembling inhalation anthrax.

Bacillus anthracis is the etiologic agent of anthrax, an acute fatal disease among mammals. It was thought to differ from Bacillus cereus, an opportunistic pathogen and cause of food poisoning, by the presence of plasmids pXO1 and pXO2, which encode the lethal toxin complex and the poly-gamma-d-glutamic acid capsule, respectively. This work describes a non-B.
