Query: NC_010334:1561691 Shewanella halifaxensis HAW-EB4, complete genome
Lineage: Shewanella halifaxensis; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from sediment in a munitions-dumping area of the Emerald Basin (depth of 215 m, Atlantic Ocean), offshore of Halifax Harbour (Nova Scotia, Canada). It is capable of efficiently degrading RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), an explosive compound that contaminates the environment. This bacterium is an obligate respiratory organism.
Subject: NC_014228:2270000 Xenorhabdus nematophila ATCC 19061, complete genome
Lineage: Xenorhabdus nematophila; Xenorhabdus; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This genus is a group of insect pathogens which live in a mutualistic relationship with the soil nematode family, Steinernematidae. Free-living, juvenile Steinernema spp. enter insect larvae through the digestive tract. They penetrate the larvae body cavity and release Xenorhabdus spp. into the hemolymph (blood). The bacteria multiply rapidly, killing the larvae, and providing suitable nutrient conditions for the growth and reproduction of the Steinernema spp. The nematode matures and reproduces. The new juveniles reassociate with Xenorhabdus spp. and are released into the soil. Unlike Xenorhabdus bovienii, which is found in different Steinernema spp., Xenorhabdus nematophila is associated specifically with Steinernema carpocapsae and can be used as a model for studying host specificity.
