Overview

  • Ileibacterium valens is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 41.1%. Ileibacterium valens is probably a rare gut coloniser. (Cox2017)



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