Overview

  • Butyricimonas faecalis is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 44.2%. Butyricimonas faecalis is probably a rare gut coloniser. (Roy2019)



  • This organism has been recovered from human faeces (Roy2019). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
