Query: NC_009256:3601080 Burkholderia vietnamiensis G4 chromosome 1, complete sequence
Lineage: Burkholderia vietnamiensis; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: B. vietnamiensis strain G4 (formerly B.cepacia strain R1808) is the best trichloroethene (TCE) co-oxidizing strain yet discovered, having been isolated from an industrial waste treatment facility at Pensacola Naval Air Station, Florida, U.S.A. Burkholderia vietnamiensis is a member of the Burkholderia cepacia complex which contains a number of closely related Burkholderia species. Burkholderia vietnamiensis is commonly isolated from soil and water and has been studied as a plant growth promoting bacterium and as a bioremediation agent for aromatic hydrocarbons such as benzene and tolulene.
Subject: NC_004631:3112043 Salmonella enterica subsp. enterica serovar Typhi Ty2, complete
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This pathogenic strain of Salmonella typhi was isolated in the early 1970s. It contains no multidrug resistance plasmids and has been used for vaccine development. This serovar is a human-specific organism that causes the life-threatening illness Typhoid fever which is acquired by coming into contact with contaminated food or water. Annually, 17 million people are infected, with 600,000 fatalities, mostly in developing countries. It contains multiple fimbrial operons that may be used to create extracellular appendages for attachment and entry into host intestinal epithelial cells. 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.
