Query: NC_010803:1132500 Chlorobium limicola DSM 245, complete genome
Lineage: Chlorobium limicola; Chlorobium; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Isolated from Gilroy Hot Spring. The green sulfur bacteria (GSB; Phylum Chlorobi ) are commonly found in illuminated, stratified, and anoxic aquatic environments, sediments, and other sulfide-rich environments including hot springs. This bacterium has been used to model a variety of enzyme and reaction center pathways, including ATP-citrate lyase, isocitrate dehydrogenase, and the reverse Krebs cycle used in photosynthesis. Now called the "reductive carbolic acid cycle", this was found to be the sole carbon dioxide assimilation pathway in other green sulfur bacteria since its discovery.
Subject: NC_010102:4745949 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.
