Overview

  • Dialister massiliensis, (aka Dialister sp. Marseille-P5638), is a Gram-negative, non-spore-forming, 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 48.4%. Dialister massiliensis is probably a rare gut coloniser. (Afouda2020a)



  • This organism has been recovered from the faeces of a healthy volunteer, France. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
