Overview

  • Clostridium roseum is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. Clostridium roseum is probably a rare gut coloniser. (Rainey2011aBergey)



  • This organism has been recovered from German maize. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
