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_012730:332500 Rickettsia peacockii str. Rustic, complete genome

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

General Information: Rickettsia peacockii was initially identified in wood ticks from the eastern side of the Bitterroot Valley in Montana. Cases of Rocky Mountain spotted fever in the Bitterroot Valley are associated with exposure to ticks from the western side. Ticks from the east side are primarily infected with R. peacockii which is nonvirulent and may prevent the establishment of pathogenic Rickettsia species in these ticks.
