Query: NC_009943:677324 Candidatus Desulfococcus oleovorans Hxd3, complete genome
Lineage: Desulfococcus oleovorans; Desulfococcus; Desulfobacteraceae; Desulfobacterales; Proteobacteria; Bacteria
General Information: An alkane-degrading sulfate-reducing Gram-negative bacterium isolated from the saline water phase of an oil-water separator from a northern German oil field. Desulfococcus oleovorans, originally designated Desulfobacterium oleovorans, was isolated using hexadecane as a carbon source and has been used to determine the mechanism of anaerobic hydrocarbon degradation.
Subject: NC_010263:278463 Rickettsia rickettsii str. Iowa, complete genome
Lineage: Rickettsia rickettsii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Causative agent for Rocky Mountain Spotted Fever. This organism was first identified by Dr. Howard Rickets as the causative agent of Rocky Mountain Spotted Fever, which was originally named for its geographic distribution at the time, it is now known to be widespread throughout the North American continent. This bacterium is an obligate intracellular pathogen that infects primarily the vascular endothelium, and occasionally smooth muscle tissue. It is passed to the human host from a tick bite, and the tick acts as both a natural reservoir and a vector for disease transmission. Once the organism is endocytosed by the host cell, it quickly escapes the phagozome, and replicates intracellularly, causing cell death and tissue damage. The disease is characterized by a spotted rash and has a high mortality rate if left untreated.
