Overview

  • Veillonella infantium is a Gram-negative, non-spore-forming, anaerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 38.6%. Veillonella infantium is probably a rare gut coloniser.



  • This organism has been recovered from the tongue biofilm of a Thai child. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
