Overview


  • Hafnia alvei is a Gram-negative, non-spore-forming, facultatively anaerobic, variably-motile, rod-shaped bacterium. It has been detected in at least 9 gut microbiome compilation studies or metastudies. The DNA G+C content is 48.0-48.7%. Hafnia alvei is probably a common, although minor, coloniser of the gut. (Farmer1985; Bascomb1971; Greipsson1983; Sakazaki2005aBergey)



  • This organism has been recovered from human faeces, clinical sources (sputum, urine, blood - CCUG) animals, sewage, water and soil. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). It is an opportunistic pathogen. Is a known gut commensal.
