Overview

  • Leptotrichia shahii, (aka Leptotrichia sp. LB37), is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, filamentous bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. Leptotrichia shahii is probably a rare gut coloniser. (Eribe2004)



  • This organism has been recovered from a patient with gingivitis. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). Can cause opportunistic infections, particularly in immunocompromised people. A possible gut commensal.
