Overview

  • Plesiomonas shigelloides is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 6 gut microbiome compilation studies or metastudies. The DNA G+C content is 51%. Plesiomonas shigelloides is probably a rare gut coloniser. (Pitarangsi1982; Janda2005aBergey)



  • This organism has been recovered from human faeces, and aquatic sources. 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.
