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_005955:841781 Bartonella quintana str. Toulouse, complete genome
Lineage: Bartonella quintana; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Bartonella quintana str. Toulouse was isolated from human blood in Toulouse, France in 1993. Causative agent of trench fever. This group of alpha proteobacteria are unique among pathogens in that they cause angiogenic lesions. This organism was first identified as the causative agent of louse-born trench fever during World War I. Up to 800 000 were infected in the trenches because of the louse insect vector that was widespread due to poor sanitation. The disease is now found associated with immunocompromized patients, especially HIV patients and homeless alcoholics.
