General Information: This strain (96-10355; K1256) is a human isolated from USA. This organism was the first to be shown to cause disease by Dr. Robert Koch, leading to the formulation of Koch's postulates, which were verified by Dr. Louis Pasteur (the organism, isolated from sick animals, was grown in the laboratory and then used to infect healthy animals and make them sick). This organism was also the first for which an attenuated strain was developed as a vaccine. Herbivorous animals become infected with the organism when they ingest spores from the soil whereas humans become infected when they come into contact with a contaminated animal. Anthrax is not transmitted due to person-to-person contact. The three forms of the disease reflect the sites of infection which include cutaneous (skin), pulmonary (lung), and intestinal. Pulmonary and intestinal infections are often fatal if left untreated. Spores are taken up by macrophages and become internalized into phagolysozomes (membranous compartment) whereupon germination initiates. Bacteria are released into the bloodstream once the infected macrophage lyses whereupon they rapidly multiply, spreading throughout the circulatory and lymphatic systems, a process that results in septic shock, respiratory distress and organ failure. The spores of this pathogen have been used as a terror weapon.

Subject: NC_003909:3606177 Bacillus cereus ATCC 10987, complete genome

Lineage: Bacillus cereus; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria

General Information: This strain was isolated in Canada during a study of cheese spoilage. Soil microorganism that can cause food poisoning. 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.
