Overview

  • Bacteroides faecis is a Gram-negative, non-spore-forming, anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 13 gut microbiome compilation studies or metastudies. The DNA G+C content is 42.7%. Bacteroides faecis is a common gut coloniser. (Kim2010; Sakamoto2015)



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