Query: NC_017066:33268 Rickettsia typhi str. TH1527 chromosome, complete genome Lineage: Rickettsia typhi; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria General Information: This genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, is composed of obligate intracellular pathogens. The latter is composed of two organisms, Rickettsia prowazekii and Rickettsia typhi. 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. This organism causes murine typhus and is an obligate intracellular pathogen that infects both the flea vector and hosts such as human, rat, and mouse. R. prowazekii, and genomic comparisons demonstrate colinearity and similarity to the genome of that organism except for two independent inversions near the origin and terminus. In the flea vector, the bacterium penetrates the gut epithelial barrier and is found in the feces which become infective.

General Information: This strain was isolated from clay soil near Hildenborough, UK in 1946. A sulfate reducing bacterium. These organisms typically grow anaerobically, although some can tolerate oxygen, and they utilize a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making these organisms of interest as bioremediators. Metal corrosion, a problem that is partly the result of the collective activity of these bacteria, produces billions of dollars in losses each year to the petroleum industry. These organisms are also responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products. This species is a sulfate reducer commonly found in a variety of soil and aquatic environments.
