Query: NC_015259:624979 Polymorphum gilvum SL003B-26A1 chromosome, complete genome
Lineage: Polymorphum gilvum; Polymorphum; ; ; Proteobacteria; Bacteria
General Information: Polymorphum gilvum SL003B-26A1 is a type strain of a newly published novel species in the novel genus Polymorphum. It was isolated from a crude oil-polluted saline soil in Shengli Oilfield, China and could use the crude oil as the sole carbon source. Oil pollution has become a global issue because of its severe ecological impact and destruction. Bioremediation is proved to be an effective process to restore the oil polluted environments. The complete genome sequence of Polymorphum gilvum SL003B-26A1 provides new strategies for bioremediation of oil contaminated environment.
Subject: NC_006142:33268 Rickettsia typhi str. Wilmington, 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. Rickettsia typhi causes murine typhus and is an obligate intracellular pathogen that infects both the flea vector and hosts such as human, rat, and mouse. In the flea vector, the bacterium penetrates the gut epithelial barrier and is found in the feces which become infective.
