Query: NC_004603:230000 Vibrio parahaemolyticus RIMD 2210633 chromosome I, complete
Lineage: Vibrio parahaemolyticus; Vibrio; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
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.
Subject: NC_009654:894492 Marinomonas sp. MWYL1, complete genome
Lineage: Marinomonas; Marinomonas; Oceanospirillaceae; Oceanospirillales; Proteobacteria; Bacteria
General Information: Marinomonas MWYL1 was isolated from the root surface of the salt marsh grass Spartina anglica, growing near the North Norfolk, England village of Stiffkey. The genus Marinomonas comprises a widespread group of g -proteobacteria that exist in coastal waters, and which had been earlier been included in the genus Alteromonas. The interest in Marinomonas MWYL 1 was that it could grow on the betaine molecule Dimethylsulphoniopropionate (DMSP) as sole carbon source and, when it did do, it released large amounts of the gas dimethyl sulphide. DMSP is a compatible solute that is used by many marine phytoplankton and seaweed macroalgae as an osmoticum and an anti-stress compound. In addition, a few known land angiosperms make DMSP and these include certain species of Spartina - hence the choice of these plants as a source for DMSP-degrading bacteria. Indeed, others had shown previously that the DMSP-catabolising bacteria isolated from Spartina root surfaces included Marinomonas strains.
