Overview

  • Duncaniella muris is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, short rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 50.8%. Duncaniella muris is probably a rare gut coloniser. (Miyake2020)



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