Lineage: Chloracidobacterium thermophilum; Chloracidobacterium; Acidobacteriaceae; ; Acidobacteria; Bacteria
General Information: This organism produces bacteriochlorophyll a and c under oxic conditions and represents a new group of photosynthetic bacteria. The only known chlorophototroph in the phylum Acidobacteria. Aerobic photoheterotroph that lacks the ability to synthesize several essential nutrients. Naturally inhabits microbial mats of alkaline siliceous hot springs in Yellowstone National Park.
Subject: NC_012633:928500 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.
