Query: NC_009050:811358 Rhodobacter sphaeroides ATCC 17029 chromosome 2, complete sequence
Lineage: Rhodobacter sphaeroides; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: A photosynthetic bacterium useful in bioremediation. Anoxygenic photosynthesis, Carbon fixation, Nitrogen fixation. Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to grow using photosynthesis, chemosynthesis, and usually can grow under both anaerobic and aerobic conditions. It can grow aerobically and anaerobically in the light and anaerobically in the dark. It produces an intracytoplasmic membrane system consisting of membrane invaginations where the light harvesting complexes (LH1 and LH2) and the reaction center are synthesized.
Subject: NC_009881:283500 Rickettsia akari str. Hartford, complete genome
Lineage: Rickettsia akari; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain was isolated from mites in Hartford. Causative agent of Rickettsialpox. 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. Rickettsia akari causes a mild disease, Rickettsialpox, which is an acute fever-inducing illness transmitted by a hematophagous mite that infects the common house mouse and bites humans. Infection by this organism may be confused with anthrax due to the black eschar. This bacterium is a member of the spotted fever group of Rickettsiales and is endemic to New York, USA, but is also found in other cities in the USA, Russia, South Korea, and South Africa.
