Overview


  • Clostridium felsineum is a Gram-positive, spore-forming, strictly anaerobic, motile, bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 26%. Clostridium felsineum is probably a rare gut coloniser. (Rainey2011fBergey)



  • This organism has been recovered from human faeces, rotting vegetation and soil. 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. Is a known gut commensal.
