Overview

  • Aeromonas sobria is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 58-60%. Aeromonas sobria is probably a rare gut coloniser. (Igbinosa2012; Popoff1976; MartinCarnahan2005Bergey)



  • This organism has been recovered from human faeces (CCUG), clinical sources (blood, wound - CCUG), fish, sewage and water. 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. A possible gut commensal.
