      Filaments exceeding 20 µm in length may occur

  • Culture characteristics

    • the following information is not yet verified

      Obligate anaerobic

      The colonies are small, translucent, or transparent, and may produce greening of the agar.

      Three colony morphotypes exist:
      1) smooth and convex
      2) pitting
      3) spreading

      All three can occur in the same culture, so they may resemble a mixed culture.
