Query: NC_009718:799431 Fervidobacterium nodosum Rt17-B1, complete genome
Lineage: Fervidobacterium nodosum; Fervidobacterium; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Fervidobacterium nodosum is a thermophilic, Gram-negative, motile, non-sporulating, glycolytic, obligately anaerobic rod that exists singly, in pairs or in chains. Fervidobacterium nodosum was isolated from a hot spring in New Zealand. Its optimal growth temperature is 65 to 70 degrees Celsius. The cellular morphology of this organism, a member of the Thermotogales, is characterized by a terminal spherical extension of the cell envelope.
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.
