Overview

  • Leptotrichia wadei is a Gram-negative, non-spore-forming, anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. Leptotrichia wadei is probably a rare gut coloniser. (Eribe2004)



  • This organism has been recovered from the saliva of a healthy volunteer. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
