Overview

  • Comamonas aquatica, (aka Aquaspirillum aquaticum), is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 62.8-66.7%. Comamonas aquatica is unlikely to be a gut coloniser. (Wauters2003)



  • This organism has been recovered from water sources. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. Likely to be transient and not a long-term gut commensal.
