      Taxonomy
      Family: Prevotellaceae

      Natural habitats
      Belong to the normal flora of the oropharynx, gastrointestinal tract, the genitals and urinary tract.

      Clinical significance
      Prevotella species are among the dominating microorganisms of the oral cavity, where they, despite their commensalism, can be involved in nearly all types of oral infections.

      Some are important pathogens in bite wounds and infections of the head, mouth, neck and lungs and they are typical polymicrobial infections.

  • Gram stain

    • the following information is not yet verified
      Gram negative coccobacilli or bacilli,

      evenly colored with rounded ends, which often occur in pairs or short chains.

      Liquid medium
      the bacteria can be more polymorphic, longer and have vacuoles

  • Culture characteristics

    • the following information is not yet verified

      Obligate anaerobic

      BBAØ
      This pigmented group is growing more slowly than the Bacteroides sp and take for the formation of pigment 2 days to 3 weeks, they are often hemolytic.

      P. corporis have dry colonies

      BBEØ no growth

      KVBAØ (BA with kanamycin and vancomycin)
      colonies are black

      Fluorescentie/woods lamp
      Brick red (that appears before the brown pigment)

      Older cultures in which the black pigment has become visible, do not fluoresce.

      The fluorescence of Prevotella is also directly in wound fluid or pus visible.
