Application

Selective medium for isolation and differentiation of pathogenic staphylococci on the basis of salt tolerance, pigmentation, D-mannitol utilization and gelatin liquefaction. Smuckler and Appleman recommend addition of sodium azide in order to make this medium selective for the determination of coagulase-positive staphylococci.
