Query: NC_009720:2143124 Xanthobacter autotrophicus Py2, complete genome
Lineage: Xanthobacter autotrophicus; Xanthobacter; Xanthobacteraceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Alkene-degrading bacterium. Xanthobacter autotrophicus is a nitrogen-fixing methylotroph, commonly isolated from organic rich soil, sediment and water. This organism uses an alkene-specific monooxygenase to convert propene to epoxypropane. This monooxygenase is also able to catalyze the initial step in the cometabolism of chlorinated alkenes such as vinyl chloride and trichloroethene. The Xanthobacter autotrophicus alkene monooxygenase and other genes involved in alkene degradation are located on a 320 kb megaplasmid.
Subject: NC_010102:283364 Salmonella enterica subsp. enterica serovar Paratyphi B str. SPB7,
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain (SGSC 4150; ATCC BAA-1250) was isolated from a stool sample of an infected woman in Penang, Malaysia, May 16, 2002. This strain is susceptible to antibiotics, and was classified as serovar Paratyphi B because it was unable to metabolize D-tartrate. Causes enteric infections. This group of Enterobactericiae have pathogenic characteristics and are one of the most common causes of enteric infections (food poisoning) worldwide. They were named after the scientist Dr. Daniel Salmon who isolated the first organism, Salmonella choleraesuis, from the intestine of a pig. The presence of several pathogenicity islands (PAIs) that encode various virulence factors allows Salmonella spp. to colonize and infect host organisms. There are two important PAIs, Salmonella pathogenicity island 1 and 2 (SPI-1 and SPI-2) that encode two different type III secretion systems for the delivery of effector molecules into the host cell that result in internalization of the bacteria which then leads to systemic spread.
