Spore formation in Bacillus anthracis and Bacillus subtilis: 
roles in survival and pathogenesis, and 
defense against biological weapons

Bacterial spores can survive even the most extreme environments. This property allows pathogenic spores, such as those produced by Bacillus anthracis, the causative agent of anthrax, to serve as biological weapons. We study the composition and assembly of spore structures responsible for their unusual durability, in both B. anthracis and B. subtilis. This work allows us to address several basic science issues, including the molecular mechanisms controlling assembly of cellular structures, and the roles of spore protective structures in pathogenesis. Our studies also allow us to contribute to a variety of efforts to defend against biological weapons, including the development of novel spore detection and decontamination methods, as well as vaccines
