Overview

  • Aeromonas allosaccharophila is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 59.5%. Aeromonas allosaccharophila is probably a rare gut coloniser. (MartinezMurcia1992; MartinCarnahan2005Bergey)



  • This organism has been recovered from human faeces, including diarrheic stools. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
