Query: NC_016779:5189139 Bacillus cereus F837/76 chromosome, complete genome
Lineage: Bacillus cereus; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: 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.
Subject: NC_009792:4017510 Citrobacter koseri ATCC BAA-895, complete genome
Lineage: Citrobacter koseri; Citrobacter; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Citrobacter koseri ATCC BAA-895 is a clinical isolate from a human infant. Causative agent of neonatal meningitis. Citrobacter koseri, previously known as Citrobacter diversus, Levinea diversus or Levinea malonatica resides in a wide range of environments, including soil, water and food products. It is an occasional inhabitant of human and animal intestines, but is mainly characterized as being a causative agent of neonatal meningitis with an extreme high rate of multiple brain abscess initiations and a concomitant high moratility rate. The bacteria are used in neonatal rat models to study the mechanism of blood-brain barrier penetration, host immune response evasion and its resistance to phagocytotic killing.
