Query: NC_016930:943000 Rickettsia philipii str. 364D chromosome, complete genome

Lineage: Rickettsia philipii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria

General Information: Rickettsiae are obligate intracellular Gram-negative bacteria mostly found in arthropods, some of which cause mild to severe diseases in humans. Spotted fever group rickettsiae (SFGR) cause disease in humans. R .philippi strain 364D, an SFGR, was isolated in 1966 from Dermacentor occidentalis ticks collected in Ventura county, California, and since then 364D has been detected in up to 11% of D. occidentalis from 8 California counties. It has now been recognized as causing eschar-associated illness.

Subject: NC_007798:213069 Neorickettsia sennetsu str. Miyayama, complete genome

Lineage: Neorickettsia sennetsu; Neorickettsia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria

General Information: This organism was first described in 1953 in Japan as causing Sennetsu fever. Causes an infectious mononucleosis-like disease. Like other Ehrlichia, this organism is an obligate intracellular pathogen. It can be transmitted from fish flukes (trematodes) to humans, and was one of the first Ehrlichia that was found to cause a human-specific illness.
