Query: NC_007799:968499 Ehrlichia chaffeensis str. Arkansas, complete genome

Lineage: Ehrlichia chaffeensis; Ehrlichia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria

General Information: This strain is the first isolate of Ehrlichia chaffeensis, which was obtained from a patient on an army base in Arkansas, USA in 1990. Causes disease in humans. This organism is an obligate intracellular pathogen that exists within vacuoles in the cytoplasm of monocytes or granulocytes. Transferred during an insect (tick) bite, it can cause disease in humans (human monocytic ehrlichiosis) and can reside in several other animals and is a problem in immunocompromised patients. The bacterium inhibits phagosome-lysozome fusion as well as programmed cell death (apoptosis) of the host cell, similar to what is observed with Anaplasma phagocytophilum.

Subject: NC_012730:1034115 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.
