Overview

  • Prevotella dentasini is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 50.2%. Prevotella dentasini is probably a rare gut coloniser. (Takada2010)



  • This organism has been recovered from oral cavity of donkeys. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
