Query: NC_012470:853561 Streptococcus equi subsp. zooepidemicus, complete genome
Lineage: Streptococcus equi; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This bacterium is part of the normal bacterial flora in horses, however, it has also been isolated from a number of other mammals including humans. S. equi subsp. zooepidemicus is the cause of Inflammatory Airway Disease (IAD) in horses. This organism is also an opportunistic pathogen which can cause infections in the upper respiratory tract, uterus, umbilicus and in open wounds. Pathogenic in horses, goats and sheep. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes.
Subject: NC_006274:4159096 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.
