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_012846:825341 Bartonella grahamii as4aup, complete genome
Lineage: Bartonella grahamii; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Bartonella grahamii (strain as4aup) is Gram-negative bacterium isolated from a wood mouse (Apodemus sylvaticus) in central Sweden. Bartonella are human and animal pathogens which infect erythrocytes and can cause angiogenic lesions. These organisms cause diseases in humans such as Oroya fever, Trench fever, endocarditis, and Cat Scratch disease. Transmission of this organism is via the bite of a blood-sucking arthropod. Bartonella grahamii can be isolated from the blood of rodents and is found world wide. Fleas may be the transmission vector for Bartonella grahamii to other rodents. Human disease appears to be rare and associated with an immunocompromised state.
