Query: NC_011244:497212 Borrelia recurrentis A1, complete genome Lineage: Borrelia recurrentis; Borrelia; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria 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.

General Information: This strain was isolated from a man with severe proctitis. This species causes infection that leads to blindness and sexually transmitted diseases in humans. There are 15 serovariants that preferentially cause disease in either the eye or the urogenital tract. The trachoma (infection of the mucous membrane of the eyelids) biovars are noninvasive and can cause blinding trachoma (variants A, B, Ba, and C), or sexually transmitted diseases (variants, D, E, F, G, H, I, J, and K). The lymphogranuloma venereum biovars (variants L1, L2, and L3) can cross the epithelial cells of mucous membranes and then travel through the lymphatic system where they multiply within mononuclear phagocytes found within the lymph nodes. Bacteria belonging to the Chlamydiales group are obligate intracellular parasites of eukaryotic cells. They are found within vertebrates, invertebrate cells, and amoebae hosts. Chlamydiae are one of the commonest causes of sexually transmitted diseases (STDs) and if left untreated may cause infertility in women. They are transmitted by direct contact or aerosols, and can cause various diseases, while also being able to coexist with the host in an apparently asymptomatic state. This species causes infection that leads to blindness and sexually transmitted diseases in humans.
