Overview

  • Veillonella montpellierensis is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. Veillonella montpellierensis is probably a rare gut coloniser. (JumasBilak2004; Carlier2011Bergey)



  • This organism has been recovered from human gastric fluid (CCUG), oral cavity, and clinical sources (endocarditis, blood - CCUG). The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). It is an opportunistic pathogen. Likely to be transient and not a long-term gut commensal. Robust growth can have negative consequences for gut health.
