Query: NC_009616:979861 Thermosipho melanesiensis BI429 chromosome, complete genome
Lineage: Thermosipho melanesiensis; Thermosipho; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: BI429 (CIP 104789) is the type strain for this species and was isolated from the gills of Bathymodiolus brevior, a deep-sea mussel. The sample was taken from the Lau Basin at the bottom of a black smoker between 1832 and 1887 metres. Thermosipho melanesiensis is a deep-sea thermophilic marine organism closely related to a hot springs isolate, T. africanus.
Subject: NC_010673:388442 Borrelia hermsii DAH, complete genome
Lineage: Borrelia hermsii; Borrelia; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: This strain was isolated from a case of relapsing fever in western Washington, USA. Borrelia hermsii is the causative agent of tick-borne relapsing fever in the western United States and Canada. Borrelia then multiplies rapidly, causing a generalized infection throughout the tick. While feeding, the tick passes the organism into a mammalian host through its infectious saliva. 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. These plasmids carry genes involved in antigenic variation and pathogenicity.
