Overview

  • Porphyromonas canoris is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, short rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 49-51%. Porphyromonas canoris is probably a rare gut coloniser. (Love1994)



  • This organism has been recovered from subgingival pockets of dogs. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
