Overview

  • Thermoclostridium stercorarium, (aka Clostridium stercorarium), is a Gram-negative, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 39-41%. Thermoclostridium stercorarium is likely to be transient and not a long-term gut coloniser. (Fardeau2001; Madden1983)



  • This organism has been recovered from compost and has been detected in human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • High optimum growth temperature so unlikely to be a gut coloniser.
