Preparation
- Columbia agar base supplemented with 5% defibrinated sheep blood. Rehydrate pellets of freeze-dried ampoules in liquid medium 545, 215 or 1 (see below).
- ATTENTION: organisms, for which only M 693 is mentioned in the catalogue entry, do not grow in one of the media listed below! Those are meant to rehydrate the freeze-dried pellets, not for cultivation.
- Adjust pH to 7.3.
- The same as Caso Bouillon (Merck or Oxoid, Germany).
- Adjust pH to 7.0.
Target organisms
No target organisms are recorded.
