Query: NC_011296:909558 Thermodesulfovibrio yellowstonii DSM 11347, complete genome
Lineage: Thermodesulfovibrio yellowstonii; Thermodesulfovibrio; Nitrospiraceae; Nitrospirales; Nitrospirae; Bacteria
General Information: This thermophilic sulfate-reducing organism was isolated from a thermal vent in Yellowstone Lake in Wyoming, USA. It has the ability to use sulfate, thiosulfate, and sulfite as terminal electron acceptors. Pyruvate can support fermentative growth.
Subject: NC_009879:260000 Rickettsia canadensis str. McKiel, complete genome
Lineage: Rickettsia canadensis; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This organism was originally isolated from ticks in a field study on tick-transmitted diseases of small mammals in Canada. Member of the typhus group of Rickettsiales. 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 canadensis 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.
