Overview

  • Brachybacterium massiliense is a Gram-positive, non-spore-forming, aerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 70.7%. Brachybacterium massiliense is probably a rare gut coloniser. (Alou2017; Mekhalif2019)



  • This organism has been recovered from human faeces (Mekhalif2019). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
