Overview

  • Prevotella salivae is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 6 gut microbiome compilation studies or metastudies. The DNA G+C content is 41.3%. Prevotella salivae is probably a rare gut coloniser. (Sakamoto2004)



  • This organism has been recovered from human faeces and saliva of patient with chronic periodontitis. 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.
