Query: NC_009997:726840 Shewanella baltica OS195, complete genome Lineage: Shewanella baltica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria General Information: This strain was isolated from the Baltic Sea. A psychrophilic bacterium. This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. This species is differentiated from other Shewanella spp. based on its ability to grow at 4 degrees C but not at 37, production of N-acetyl-beta-glucosaminidase, lack of chymotrypsin, and ability to use a variety of complex carbon compounds as carbon and energy sources.

General Information: This is a clinical strain isolated in 1996 in Osaka, Japan. It contains a type III secretion system which may enable colonization and penetration of the host intestinal epithelial layer, and possibly lead to septicemia. The genome contains multipe chromosomal rearrangements as compared to Vibrio cholerae. The organism also produces a hemolysin (thermostable direct hemolysin - TDH) that is particular to Vibrio parahaemolyticus. This genus is abundant in marine or freshwater environments such as estuaries, brackish ponds, or coastal areas; regions that provide an important reservoir for the organism in between outbreaks of the disease. Vibrio can affect shellfish, finfish, and other marine animals and a number of species are pathogenic for humans. This species causes food poisoning (gastroenteritis) in countries that have elevated levels of seafood consumption such as Japan.
