Overview

  • Robertmurraya massiliosenegalensis, (aka Bacillus massiliosenegalensis), is a Gram-positive, spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 37.6%. Robertmurraya massiliosenegalensis is probably a rare gut coloniser. (Ramasamy2013)



  • This organism has been recovered from human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal. Robust growth can have positive consequences for gut health.
