Query: NC_014933:364463 Bacteroides helcogenes P 36-108 chromosome, complete genome
Lineage: Bacteroides helcogenes; Bacteroides; Bacteroidaceae; Bacteroidales; Bacteroidetes; Bacteria
General Information: Environment: Host; Isolation: Pig faeces; Temp: Mesophile. This group of microbes constitute the most abundant members of the intestinal microflora of mammals. Typically they are symbionts, but they can become opportunistic pathogens in the peritoneal (intra-abdominal) cavity. This organism produces many extracellular enzymes which assist in the breakdown of complex plant polysaccharides such as cellulose and hemicellulose and host-derived polysaccharides such as mucopolysaccharides. This species has been isolated from abscesses in pigs.
Subject: NC_006274:5267585 Bacillus cereus E33L, complete genome
Lineage: Bacillus cereus; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: This strain (originally ZK, now E33L; Ethosha National Park, Namibia; isolate number 33; Large colony) was isolated from a swab of a dead zebra carcass in April, 1996. 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.
