Overview

  • Acetatifactor muris is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 48.5%. Acetatifactor muris is probably a rare gut coloniser. (Pfeiffer2012)



  • This organism has been recovered from caecal contents of a mouse. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
