  • Culture characteristics

    • the following information is not yet verified

      Obligate anaerobic

      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.
