Overview

  • Vibrio metschnikovii is a Gram-negative, non-spore-forming, facultatively anaerobic, variably-motile, rod-shaped - curved bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 44-46%. Vibrio metschnikovii is probably a rare gut coloniser. (Farmer2005gBergey)



  • This organism has been recovered from brackish waters, fowl and (rarely) clinical sources (blood). The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: zoonotic pathogen). Is a rare opportunistic pathogen. A possible gut commensal.
