Query: NC_017058:497500 Rickettsia australis str. Cutlack chromosome, complete genome
Lineage: Rickettsia australis; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Animal pathogen in Mammalia (intracellular obligate). Rickettsiae are obligate intracellular Gram-negative bacteria mostly found in arthropods, some of which cause mild to severe diseases in humans. Rickettsia australis causes a medical condition called Queensland tick typhus. The probable vectors are the tick species, Ixodes holocyclus and Ixodes tasmani. Small marsupials are suspected reservoirs of this bacterium.
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.
