Overview


  • Massilimicrobiota timonensis is a Gram-negative, non-spore-forming, strictly 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 31.8%. Massilimicrobiota timonensis is a common gut coloniser. (Tall2019)



  • This organism has been recovered from human faeces (Tall2019). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
