Overview

  • Prevotella aurantiaca 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 39.7%. Prevotella aurantiaca is probably a rare gut coloniser.



  • This organism has been recovered from periodontal pockets of a patient with periodontitis. Can cause opportunistic infections, particularly in immunocompromised people. A possible gut commensal.
