Query: NC_013515:550464 Streptobacillus moniliformis DSM 12112, complete genome
Lineage: Streptobacillus moniliformis; Streptobacillus; Leptotrichiaceae; Fusobacteriales; Fusobacteria; Bacteria
General Information: Isolation: Patient with rat-bite fever in France; Temp: Mesophile; Temp: 37C; Habitat: Host. Streptobacillus moniliformis causes rat bite fever, a systemic illness characterized by fever, chills, and joint pain which can progress to endocarditis, meningitis or pneumonia if left untreated. Although infection is usually associated with a rodent bite, this disease can be caused by ingestion of contaminated food or water. Streptobacillus moniliformis is the causative agent of rat bite fever in North and South America while a different organism, Spirillum minus, is primarily responsible for this disease in Asia and other countries.
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.
