Overview

  • Agathobacter ruminis is a Gram-positive, non-spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 41-42%. Agathobacter ruminis is probably a rare gut coloniser. (Rosero2016)



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