Lineage: Paracoccus denitrificans; Paracoccus; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This organism is commonly found in soil and sewage sludge. This organism is able to survive in both aerobic and anaerobic environments due to its ability to use both oxygen and nitrogenous oxides making it a popular model organism for the study of electron transfer and and energy conservation.
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.
