Overview

  • Clostridium carnis is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. The DNA G+C content is 28%. Clostridium carnis is probably a rare gut coloniser. (Rainey2011aBergey)



  • This organism has been recovered from human faeces (Rainey2011aBergey), clinical specimens, soil and putrefying meat. 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. Is a known gut commensal.
