Query: NC_003910:2175305 Colwellia psychrerythraea 34H, complete genome
Lineage: Colwellia psychrerythraea; Colwellia; Colwelliaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from Arctic marine sediments. Psychrophilic bacterium. This obligately psychrophilic red-pigmented organism is often found in sea ice, and can grow in temperatures down to -5 C, remaining motile even at those low temperatures. It can produce extracellular enzymes such as proteases that have activity at very low temperatures.
Subject: NC_003198:2109775 Salmonella enterica subsp. enterica serovar Typhi str. CT18,
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: 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.
