A greater percentage of DNase-positive strains was detected with DNase test agar than with DNase test agar containing 0.005% methyl green or 0.005% toluidine blue (P < 0.01). No significant differences were obtained in the percentage of phosphatase-positive strains with the four methods compared. On the basis of ease of use, P agar containing para-nitrophenylphosphate disodium (0.495 mg/ml) would be the preferred method for determining phosphatase activity of staphylococci.
