Overview

  • Prevotella histicola is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 43%. Prevotella histicola is probably a rare gut coloniser.



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