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.
