Overview

  • Beduini massiliensis is a Gram-negative, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 35.9%. Beduini massiliensis is probably a rare gut coloniser. (Mourembou2015)



  • This organism has been recovered from human faeces (Mourembou2015). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
