Overview

  • Olsenella massiliensis is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 63-64%. Olsenella massiliensis is probably a rare gut coloniser. (Sakamoto2019; Zgheib2021)



  • This organism has been recovered from human faeces (Lagier2016). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
