Overview

  • Porphyromonas bennonis is a Gram-negative, non-spore-forming, strictly anaerobic, rod-shaped bacterium. It has been detected in at least 6 gut microbiome compilation studies or metastudies. The DNA G+C content is 58%. Porphyromonas bennonis is probably a rare gut coloniser. (Hahnke2016; Summanen2009)



  • This organism has been recovered from human faeces (Bilen2018e) and clinical sources (shoulder abscess - CCUG). It is an opportunistic pathogen. A possible gut commensal.
