Query: NC_011725:3862094 Bacillus cereus B4264 chromosome, complete genome
Lineage: Bacillus cereus; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: This strain was isolated in 1969 from a case of fatal pneumonia in a male patient. B. cereus B4264 was cultured from the blood and the pleural fluid. This organism is a soil-dwelling opportunistic pathogen that causes food poisoning in infected individuals. The rapid onset is characterized by nausea and vomiting while the late onset is characterized by diarrhea and abdominal pain. The emetic disease is caused by a small stable dodecadepsipeptide cerulide whereas the diarrheal disease is caused by a heat labile enterotoxin. Some strains produce a potent cytotoxin that forms a pore in the membrane of eukaryotic cells and causes necrotic enteritis (death of intestinal epithelial cells) while the unique tripartite membrane lytic toxin hemolysin BL contributes to the diarrheal disease and destructive infections of the eye.
