Query: NC_016929:851044 Rickettsia canadensis str. CA410 chromosome, complete genome

Lineage: Rickettsia canadensis; 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 organism was originally thought to be a member of the typhus group of Rickettsiales, however, it is now thought to represent a distict group with the rickettsia.

Subject: NC_011653:1226035 Thermosipho africanus TCF52B, complete genome

Lineage: Thermosipho africanus; Thermosipho; Thermotogaceae; Thermotogales; Thermotogae; Bacteria

General Information: This organism was isolated from the Troll oil formation in the North Sea. Thermosipho africanus, a member of the Thermotogales, has the characteristic morphology of one or more cells contained in a sheath-like envelope which extends beyond the cell wall. Preliminary sequencing of Thermotogales genomes has identified extensive horizontal gene transfer between these organisms and the Archaea. Thermosipho africanus has been isolated from marine hydrothermal systems and oil reservoir production waters.
