General Information: Isolation: mud in British Guyana; Temp: Mesophile; Temp: 37 C; Habitat: Mud. Desulfovibrio are sulfate-reducing bacteria which reduce sulfate to sulfide found in soil, freshwater, saltwater and the intestinal tract of animals. These organisms typically grow anaerobically, although some can tolerate oxygen, and they utilize a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite, as well as others. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making these organisms of interest as bioremediators. These organisms are responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products.
Subject: NC_008570:1094442 Aeromonas hydrophila subsp. hydrophila ATCC 7966, complete genome
Lineage: Aeromonas hydrophila; Aeromonas; Aeromonadaceae; Aeromonadales; Proteobacteria; Bacteria
General Information: Isolated from canned milk from the USA. Aquatic organism that can cause foodborne illnesses in humans. This organism is an enviromental bacterium that is often found in aquatic habitats, but can also be found contaminating food products. It causes a variety of diseases in both cold-blooded and warm-blooded organisms. The bacterium is becoming a problematic pathogen in humans, where it causes gastroenteritis and septicemia, mainly due to the development of antibiotic resistance by this organism. One of the major virulence factors is aerolysin, a toxin that is produced and secreted by the cell via a type II secretion apparatus. Other virulence functions include a surface layer which inhibits complement-mediated killing, type IV pili for attachment, and a set of extracellular proteases which can cause tissue damage.
