Overview

  • Aeromonas eucrenophila is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 59.8-62.6%. Aeromonas eucrenophila is unlikely to be a gut coloniser. (Igbinosa2012; Schubert1988; MartinCarnahan2005Bergey; Huys1997)



  • This organism has been recovered from human faeces (CCUG), fresh uncontaminated brooks and Rivers. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: human and animal pathogen; opportunistic in immunocompromised patients). It is an opportunistic pathogen. Likely to be transient and not a long-term gut commensal.
