Overview

  • Vibrio mimicus is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. Vibrio mimicus is probably a rare gut coloniser. (Davis1981; Farmer2005gBergey)



  • This organism has been recovered from human faeces, and clinical sources (diarrhoea, ear infections - CCUG). 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). It is an opportunistic pathogen. A possible gut commensal.
