Overview

  • Eubacterium ruminantium is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. Eubacterium ruminantium is probably a rare gut coloniser. (Wade2011Bergeys)



  • This organism has been recovered from human faeces and cow rumen. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
