Query: NC_009831:1255995 Shewanella sediminis HAW-EB3, complete genome
Lineage: Shewanella sediminis; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: Shewanella sediminis was isolated from sediment taken at a depth of 215 meters from an unexploded-ordinance-dumping site 50 nautical miles from Halifax Harbor, Canada in the Atlantic Ocean. This organism is able to degrade hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) anaerobically at 10 degrees C. RDX is a member of a family of nitramine compounds which are used in the production of explosives. Shewanella are facultatively anaerobic, Gram-negative bacteria, motile by polar flagella, rod-like, and generally associated with aquatic or marine environments.
Subject: NC_004603:370320 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.
