Query: NC_006142:811469 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.

Subject: NC_005823:3454000 Leptospira interrogans serovar Copenhageni str. Fiocruz L1-130

Lineage: Leptospira interrogans; Leptospira; Leptospiraceae; Spirochaetales; Spirochaetes; Bacteria

General Information: This strain was isolated from a patient with severe leptospirosis during an epidemic in 1996. This organism is the causative agent of leptospirosis, a tropical zoonosis transmitted by direct contact with the urine of infected animals. This motile and obligately aerobic organism grows optimally at 28-30 C. Many serovars are adapted for specific mammalian reservoir hosts, which harbor the organisms in their renal tubules and shed them in their urine. Because of the large spectrum of animal species that serve as reservoirs, leptospirosis is considered to be the world's most widespread zoonotic disease.
