Overview

  • Actinosynnema mirum is a Gram-positive, exosporous, aerobic, motile, filamentous bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. Actinosynnema mirum is unlikely to be a gut coloniser. (Hasegawa1978)



  • This organism has been recovered from river grass blades, USA. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Aerobic and inability to grow at 37C suggests this not a gut coloniser.
