Query: NC_016931:171444 Rickettsia massiliae str. AZT80 chromosome, complete genome

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

General Information: 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. This bacterium is a member of the spotted fever group of the Rickettsiales and has been isolated from ticks in Europe and Africa. Rickettsia massiliae does not appear to cause disease in humans.

Subject: NC_010803:2444120 Chlorobium limicola DSM 245, complete genome

Lineage: Chlorobium limicola; Chlorobium; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria

General Information: Isolated from Gilroy Hot Spring. The green sulfur bacteria (GSB; Phylum Chlorobi ) are commonly found in illuminated, stratified, and anoxic aquatic environments, sediments, and other sulfide-rich environments including hot springs. This bacterium has been used to model a variety of enzyme and reaction center pathways, including ATP-citrate lyase, isocitrate dehydrogenase, and the reverse Krebs cycle used in photosynthesis. Now called the "reductive carbolic acid cycle", this was found to be the sole carbon dioxide assimilation pathway in other green sulfur bacteria since its discovery.
