Overview

  • Veillonella denticariosi is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, coccus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. Veillonella denticariosi is probably a rare gut coloniser. (Byun2007)



  • This organism has been recovered from carious dentine. 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.
