Overview

  • Treponema parvum is a Gram-negative, non-spore-forming, strictly anaerobic, motile, spirochete bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. Treponema parvum is likely to be transient and not a long-term gut coloniser. (Wyss2001)



  • This organism has been recovered from a deep periodontal lesion. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Is a rare opportunistic pathogen. Likely to be transient and not a long-term gut commensal.
