Overview

  • Bifidobacterium faecale is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 58.6%. Bifidobacterium faecale is probably a rare gut coloniser. (Choi2014)



  • This organism has been recovered from human faeces (Choi2014). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
