General Information: Borrelia recurrentis isolated from adult patient with louse-borne relapsing fever in Ethiopia. Borrelia recurrentis is the causative agent of louse-borne relapsing fever. Prior to World War II, this organism was responsible for large disease outbreaks with a mortality of up to 40% in much of the world. Currently this disease is limited to parts of Africa, China, and Peru. B. recurrentis is transmitted when infected human body lice (Pediculus humanus) are crushed and their fluids contaminate mucous membranes or breaks in the skin. Relapsing fever is characterized by a period of chills, fever, headache, and malaise, an asymptomatic period, followed by another episode of symptoms. This 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.

Subject: NC_009465:171000 Candidatus Vesicomyosocius okutanii HA, complete genome

Lineage: Calyptogena okutanii thioautotrophic gill symbiont; sulfur-oxidizing symbionts; ; sulfur-oxidizing symbionts; Proteobacteria; Bacteria

General Information: This strain was collected off Hatsushima island in Sagami Bay, Japan. Calyptogena okutanii (deep-sea clam) thioautotrophic gill symbiont. The bivalve marine species Calyptogena okutanii depends on sulfur-oxidizing symbiotic bacteria housed in its gill tissues for its sole nutritional support. The symbiont is transmitted vertically between generations via the clam's eggs. This anaerobic symbiosis oxidizes hydrogen sulfide as an energy source and fixes carbon dioxide into organic compounds.
