Query: NC_012115:1415827 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.
Subject: NC_009802:1077926 Campylobacter concisus 13826, complete genome
Lineage: Campylobacter concisus; Campylobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: Campylobacter concisus 13826 is a gastrointestinal clinical isolate. Members of this genus are one of the most common causes of bacterial gastroenteritis (campylobacteriosis). Usually the symptoms are abdominal pain, fever, diarrhea, and cramps, but the illness can sometimes be fatal and some infected individuals develop a syndrome (Guillain-Barre) in which the nerves connecting the spinal cord to the brain are damaged. C. jejuni is the main cause of campylobacteriosis, but other species can also cause infection, including C. coli, C. upsaliensis, and C. concisus. Campylobacter concisus was first isolated from the human oral cavity in cases of gingivitis; however the role it plays in periodontal disease is unclear. This organism has also been isolated from children and immunocompromised patients with gastrointestinal disease. C. concisus is a genetically diverse species, comprised of at least four genomospecies.
