Query: NC_017056:804416 Rickettsia prowazekii str. BuV67-CWPP chromosome, complete genome
Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This species is the causal agent of typhus. The bacteria are transmitted via an insect, usually a tick, to a host organism, in this case humans, 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. Transovarial transmission (from mother to offspring) occurs in the invertebrate host.
Subject: NC_007940:1138324 Rickettsia bellii RML369-C, complete genome
Lineage: Rickettsia bellii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain (RML 369-C) was isolated in embryonated chicken eggs from a triturated (powdered) pool of unfed adult Dermacentor variabilis ticks collected from vegetation near Fayetteville, Arkansas, USA, in 1966. Transmitted via American ticks. This organism represents the third group of Rickettsial species and is separate from the spotted fever group and the typhus group. This organism is transovarially transmitted in American ticks and shows the largest range of host organisms including Dermacentor and Amblyomma.
