Overview

  • Colibacter massiliensis is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, diplococci bacterium. The DNA G+C content is 50.2%. Colibacter massiliensis is probably a rare gut coloniser. (Anani2019)



  • This organism has been recovered from human faeces (Anani2019). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
