Overview

  • Anaerotignum faecicola is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. The DNA G+C content is 47.3%. Anaerotignum faecicola is probably a rare gut coloniser. (Choi2019)



  • This organism has been recovered from human faeces (Choi2019). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
