Query: NC_007798:213069 Neorickettsia sennetsu str. Miyayama, complete genome
Lineage: Neorickettsia sennetsu; Neorickettsia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This organism was first described in 1953 in Japan as causing Sennetsu fever. Causes an infectious mononucleosis-like disease. Like other Ehrlichia, this organism is an obligate intracellular pathogen. It can be transmitted from fish flukes (trematodes) to humans, and was one of the first Ehrlichia that was found to cause a human-specific illness.
Subject: NC_012115:1122905 Nautilia profundicola AmH, complete genome
Lineage: Nautilia profundicola; Nautilia; Nautiliaceae; Nautiliales; Proteobacteria; Bacteria
General Information: Thermophilic sulfur-reducing bacterium. Nautilia can be isolated from the epidermis of the hydrothermal vent worm, Alvinella pompejana and from hydrothermal vent chimneys. These organisms grow chemoautotrophically on hydrogen, sulfur, and CO2. Nautilia profundicola is a thermophilic, hydrogen-oxidizing, sulfur-reducing chemoautotroph that uses the reductive TCA cycle for carbon fixation. It is a member of the deepest branch of the Epsilonproteobacteria and is a model organism of the anaerobic autotrophic Epsilonproteobacteria at hydrothermal vents.
