Query: NC_006511:854785 Salmonella enterica subsp. enterica serovar Paratyphi A str. ATCC

Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This serovar has a narrow host range and causes a typhoid-like (paratyphoid fever) illness in humans. It is especially prevalent in southern and eastern Asia, and has been associated with some particularly virulent outbreaks. A number of isolates are increasingly antibiotic resistant. 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.

Subject: NC_006576:1551939 Synechococcus elongatus PCC 6301, complete genome

Lineage: Synechococcus elongatus; Synechococcus; Synechococcaceae; Chroococcales; Cyanobacteria; Bacteria

General Information: Freshwater organism. These unicellular cyanobacteria are also known as blue green algae and along with Prochlorococcus are responsible for a large part of the carbon fixation that occurs in marine environments. Synechococcus have a broader distribution in the ocean and are less abundant in oligotrophic (low nutrient) regions. These organism utilize photosystem I and II to capture light energy. They are highly adapted to marine environments and some strains have evolved unique motility systems in order to propel themselves towards areas that contain nitrogenous compounds. An obligate photoautotroph, it has been studied extensively by an international research community with respect to acquisition of organic carbon, transport and regulation of nitrogen compounds, adaptation to nutrient stresses, and reponse to light intensity.
