Overview


  • Prevotella denticola, (aka Bacteroides denticola), is a Gram-negative, non-spore-forming, anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 11 gut microbiome compilation studies or metastudies. The DNA G+C content is 49-51%. Prevotella denticola is probably a common, although minor, coloniser of the gut. (Shah1990; Wu1992; Shah2010Bergeys; Shah1981; Watabe1983a)



  • This organism has been recovered from oral cavity and human faeces. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). It is an opportunistic pathogen. A possible gut commensal.

  • GutFeeling KnowledgeBase COMMENTS [Website]

    Cells are nonmotile, non-spore-form- ing, gram-negative, blunt-ended, oval rods that are 0.7 by 1 to 2 p,m. They occur singly. Peritrichous fimbrae and a thick capsulelike structure are present. Obligately anaerobic. Poor growth occurs in liquid media; better growth occurs on blood agar media supplemented with hemolyzed blood. No growth occurs on kanamycin-vancomycin laked blood agar. [PMID: 7547307] Prevotella denticola is isolated from the human mouth, where it is suspected to cause disease. This strain has been sequenced as part of the Human Microbiome Project (HMP).
