Symposium on microbiology update: old friends and new enemies. Bacillus cereus.
Bacillus cereus is an environmentally ubiquitous, Gram-positive, spore-forming bacillus responsible for 2 distinct foodborne disease syndromes as well as other manifestations of pathogenicity. The rapid-onset, "emetic," foodborne-disease syndrome is associated with an emetic toxin; the delayed-onset, "diarrheal" syndrome is associated with elaboration of enterotoxin. The majority of methods for detection of these toxins have relied on in vivo testing. More recent work on purification of enterotoxin facilitated the development of a rapid, specific, fluorescent immunodot assay and a tissue culture screening assay for enterotoxin. Work on characterization and detection of emetic toxin is ongoing.
