Query: NC_008343:2020785 Granulibacter bethesdensis CGDNIH1, complete genome
Lineage: Granulibacter bethesdensis; Granulibacter; Acetobacteraceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Isolated from a patient with fever and lymphadenitis. Chronic granulomatous disease (CGD) is a rare inherited disease of the phagocyte NADPH oxidase system causing defective production of toxic oxygen metabolites, impaired bacterial and fungal killing, and recurrent life-threatening infections. This species was isolated from a 39 year old man with CGD and was shown to be the causal agent of the disease by classical methods. The isolation of this organism is the first known case of a bacterium from the Acetobacteraceae family to be the cause of an invasive human disease.
Subject: NC_012633:276500 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.
