Preparation

  1. Columbia agar base supplemented with 4% horse blood. Rehydrate pellets of freeze-dried ampoules in liquid medium 545, 215 or 1 (see below). For rehydration of Helicobacter and Campylobacter spp., use medium 215 (brain heart infusion).
  2. Adjust pH to 7.3.
  3. The same as Caso Bouillon (Merck or Oxoid, Germany).
  4. Adjust pH to 7.0.
