Query: NC_012730:293634 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.
Subject: NC_012026:75812 Anaplasma marginale str. Florida, complete genome
Lineage: Anaplasma marginale; Anaplasma; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Anaplasma marginale str. Florida. was isolated from pooled blood samples from naturally infected cattle in Florida. The Florida strain is virulent and non-tick transmitted. This organism is the causative agent of bovine anaplasmosis and is an obligate intracellular pathogen. Transmission occurs via an arthropod vector (tick) and is a major problem in tropical regions where it causes severe morbidity in cattle populations. The bacterium lives intracellularly within membrane-bound vesicles in the host erythrocyte, a cell type which it specifically targets, resulting in severe anemia for the host organism.
