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_010645:3720501 Bordetella avium 197N, complete genome

Lineage: Bordetella avium; Bordetella; Alcaligenaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: This strain is a spontaneous nalidixic acid-resistant derivative of virulent strain 197. This group of organisms is capable of invading the respiratory tract of animals and causing severe diseases. They express a number of virulence factors in order to do this including filamentous hemagglutins for attachment, cytotoxins, and proteins that form a type III secretion system for transport of effector molecules into host cells. This organism infects the respiratory tract of birds, and causes bordetellosis in commercially important animals such as turkeys, resulting in devastating losses every year due to secondary infections.
