Overview


  • Aeromonas enteropelogenes, (aka Aeromonas trota), is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 5 gut microbiome compilation studies or metastudies. Aeromonas enteropelogenes is probably a rare gut coloniser. (Igbinosa2012; Carnahan1991; MartinCarnahan2005Bergey)



  • This organism has been recovered from human faeces and appendix. 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.
