Query: NC_012633:169444 Rickettsia africae ESF-5, complete genome

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

General Information: This organism was isolated from a cattle tick, Amblyomma variegatum, collected in Ethiopia. This organism, a member of the spotted fever group of the Rickettsiales, is found in sub-Saharan Africa and the Caribbean. Rickettsia africae causes a flu-like illness, characterized by a mild fever and severe headache, without the skin rash common to other spotted fever group Rickettsia species. Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms.

Subject: NC_008783:671349 Bartonella bacilliformis KC583, complete genome

Lineage: Bartonella bacilliformis; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: Cauative agent of Carrion's disease. Like other members of this genus, Bartonella bacilliformis is an obligate intracellular parasite, which infects red blood cells. Bartonella bacilliformis is the causative agent of Carrion's disease, also called Oroya fever. This disease is found in the western Andes of South America, and is transmitted through an insect vector. Carrion's disease is characterized by an acute, febrile, anemia with a mortality of 40 to 90%. The anemic phase may be followed by a milder secondary episode, characterized by wart-like skin lesions.
