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.

General Information: This strain is a human clinical isolate from a human burn patient. It is infectious in mice, Caenorhabditis elegans, Drosophila melanogaster, and Arabidopsis thaliana. Opportunistic pathogen. Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. This organism is an opportunistic human pathogen. While it rarely infects healthy individuals, immunocompromised patients, like burn victims, AIDS-, cancer- or cystic fibrosis-patients are at increased risk for infection with this environmentally versatile bacteria. It is an important soil bacterium with a complex metabolism capable of degrading polycyclic aromatic hydrocarbons, and producing interesting, biologically active secondary metabolites including quinolones, rhamnolipids, lectins, hydrogen cyanide, and phenazines. Production of these products is likely controlled by complex regulatory networks making Pseudomonas aeruginosa adaptable both to free-living and pathogenic lifestyles. The bacterium is naturally resistant to many antibiotics and disinfectants, which makes it a difficult pathogen to treat.
