Overview

  • Aeromonas veronii is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 57-58%. Aeromonas veronii is probably a rare gut coloniser. (HickmanBrenner1987; Igbinosa2012; MartinCarnahan2005Bergey)



  • This organism has been recovered from human faeces (CCUG), including diarrhoea, animals and aquatic sources. 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). Is a known human pathogen. A possible gut commensal.
