A very nutritious general-purpose medium based on Columbia Agar Base enriched with 5% Sheep Blood, suitable for the isolation of most organisms including most fastidious anaerobes of clinical significance. Many workers claim that β-haemolysis is more readily apparent, particularly in group A streptococci, when Sheep Blood is used in place of Horse Blood.
