Bacillus anthracis pdf

Bacillus anthracis is the causative agent of anthrax, a disease of animals that is transmissible to humans. Because B. anthracis forms spores that can be aerosolized and sprayed with the intent to kill, this pathogen can also be viewed as an agent of biological warfare and bioterrorism ( 1 ).

Feb 01, 2007 · Bacillus spp. and Clostridium spp. form a specialized cell type, called a spore, during a multistep differentiation process that is initiated in response to starvation. Spores are protected by a morphologically complex protein coat. The Bacillus anthracis coat is of particular interest because the spore is the infective particle of anthrax. We determined the roles of several B. anthracis Bacillus cereus Related Species The genus Bacillus is divided into three broad groups, depending on the morphologyofthe spore and sporangium, a scheme that wasoriginally proposed bySmith et al. (147) and developed further in 1973 (66).
