Query: NC_008710:703740 Borrelia turicatae 91E135, complete genome

Lineage: Borrelia turicatae; Borrelia; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria

General Information: This strain was isolated in the USA from the soft tick Ornithodoros turicatae. Borrelia turicatae is the causative agent of tick-borne relapsing fever in the southwestern USA. Ticks become infected with Borrelia while feeding on an infected mammal, usually a rodent or squirrel. Borrelia then multiplies rapidly, causing a generalized infection throughout the tick. While feeding, the tick passes the spirochete into a mammalian host through its infectious saliva. Relapsing fever is characterized by period of chills, fever, headache, and malaise, followed by an asymptomatic, followed by another episode of symptoms. The cycle of relapsing is due to changes in the surface proteins of Borrelia, which allow it to avoid detection and removal by the host immune system. This antigenic variation is the result of homologous recombination of silent proteins into an expressed locus, causing partial or complete replacement of one serotype with another. These plasmids carry genes involved in antigenic variation and pathogenicity.

Subject: NC_008820:2595500 Prochlorococcus marinus str. MIT 9303, complete genome

Lineage: Prochlorococcus marinus; Prochlorococcus; Prochlorococcaceae; Prochlorales; Cyanobacteria; Bacteria

General Information: This strain was collected from the Sargasso Sea at a depth of 100 m and was isolated by filter fractionation. It can grow only in a narrow range of light intensities. This strain belongs to the 'low light-adapted' ecotype, clade IV, and has a high Chl b/a2 ratio. Marine cyanobacterium. This non-motile bacterium is a free-living marine organism that is one of the most abundant, as well as the smallest, on earth, and contributes heavily to carbon cycling in the marine environment. This cyanobacterium grows in areas of nitrogen and phosphorus limitation and is unique in that it utilizes divinyl chlorophyll a/b proteins as light-harvesting systems instead of phycobiliproteins. These pigments allow harvesting of light energy from blue wavelengths at low light intensity.
