Overview

  • Leptotrichia hofstadii is a Gram-negative, non-spore-forming, anaerobic, non-motile, rod-shaped - curved bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. Leptotrichia hofstadii 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. A possible gut commensal.
