General Information: Salmonella enterica subsp. enterica serovar Enteriditis str. P125109 is a virulent phage type 4 strain. 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.

Subject: NC_005125:760721 Gloeobacter violaceus PCC 7421, complete genome

Lineage: Gloeobacter violaceus; Gloeobacter; ; Gloeobacterales; Cyanobacteria; Bacteria

General Information: This organism was isolated from a calcereous (chalky) rock in Switzerland. Photosynthetic bacterium. This organism is an obligate photoautotroph that lacks thylakoid membranes and probably has its photosynthetic machinery in the cytoplasmic membrane with various components exposed to the periplasm whereas in other cyanobacteria the components are situated in the thylakoid membrane and are exposed to the cytoplasm. This unusual arrangement may be due to the lack of various fatty acids that are found in the thylakoid membrane in other cyanobacteria. It has been predicted that this organism was one of the earliest to diverge from the cyanobacterial line.
