Overview

  • Centipeda periodontii is a Gram-negative, non-spore-forming, strictly anaerobic, motile, rod-shaped - curved bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 52-54%. Centipeda periodontii is probably a rare gut coloniser.



  • This organism has been recovered from periodontal lesions. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Can cause opportunistic infections, particularly in immunocompromised people. A possible gut commensal.
