Preparation

  1. 1. Suspend 44 g Columbia Blood Agar Base in 1l deionized water. Heat to boiling to dissolve completely.
  2. 2. Sterilize by autoclaving for 15 min at 121°C.
  3. 3. Cool to 45°C. Add 5% sterile defibrinated sheep blood and mix well.
  4. Rehydrate pellets of freeze-dried ampoules in liquid medium 220 (see below).
  5. Adjust pH to 7.3. Medium is identical with Tryptone Soya Agar (Oxoid Cm131).
