Overview

  • Anaerostipes butyraticus is a Gram-positive, 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 44%. Anaerostipes butyraticus is probably a rare gut coloniser. (Eeckhaut2010)



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