Overview

  • Scardovia wiggsiae is a Gram-positive, non-spore-forming, anaerobic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 55%. Scardovia wiggsiae is probably a common, although minor, coloniser of the gut.



  • This organism has been recovered from the human oral cavity and clinical sources. Can cause opportunistic infections, particularly in immunocompromised people. A possible gut commensal.
    • QUIRKS
  • In 15% of Europeans (unseenbio.com). Minor coloniser.
