Overview

  • Bifidobacterium mongoliense is a Gram-positive, non-spore-forming, facultatively 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 61.1-61.9%. Bifidobacterium mongoliense is likely to be transient and not a long-term gut coloniser. (Watanabe2009; Milani2019)



  • This organism has been recovered from human faeces, and fermented mare's milk. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Known to temporarily colonise the human gut through the ingestion of parmesan cheese. Unlikely long-term gut coloniser.
