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.

Subject: NC_009879:141000 Rickettsia canadensis str. McKiel, complete genome

Lineage: Rickettsia canadensis; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria

General Information: This organism was originally isolated from ticks in a field study on tick-transmitted diseases of small mammals in Canada. Member of the typhus group of Rickettsiales. Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Rickettsia canadensis was originally thought to be a member of the typhus group of Rickettsiales, however, it is now thought to represent a distict group with the rickettsia.
