CCDA Medium is based on the original formulation described by Bolton et al. which was developed to replace blood with charcoal, ferrous sulphate and sodium pyruvate. Improved selectivity was achieved when cephazolin in the original formulation was replaced by Cefoperazone as the selective agent. More recent work has shown an increased isolation rate can be achieved if the plates are incubated at 37C rather than 42C. Amphotericin B has been added to the formula to suppress the growth of yeast and fungal contaminants that may occur at 37C.
