Overview


  • Providencia rettgeri, (aka Proteus rettgeri), is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 7 gut microbiome compilation studies or metastudies. The DNA G+C content is 40.5%. Providencia rettgeri is probably a common, although minor, coloniser of the gut. (Farmer1985; Ewing1962; O'Hara2000; Shaw1955; Penner2005aBergey)



  • This organism has been recovered from human faeces and clinical sources (blood, urine, sputum, wound, atherosclerotic plaques). The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. A possible gut commensal. Robust growth can have negative consequences for gut health.
