Overview

  • Clostridium chauvoei is a Gram-positive, spore-forming, strictly anaerobic, motile, pleiomorphic bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 27%. Clostridium chauvoei is probably a rare gut coloniser. (Hall1922; Willis1972; Rainey2011aBergey)



  • This organism has been recovered from human faeces, soil, and various animal gut. 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. Likely to be transient and not a long-term gut commensal.
