Overview

  • Treponema pectinovorum is a Gram-negative, non-spore-forming, strictly anaerobic, motile, helical-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 39%. Treponema pectinovorum is probably a rare gut coloniser. (Smibert1983)



  • This organism has been recovered from a patient with peridontal disease. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
