descending order were: (1) tellurite polymyxin egg yolk agar, (2) Baird-Parker's egg-tellurite-glyoine-pyruvate-agar, (3) tellurite glycine agar, (4) tellurite egg yolk agar, and (5) staphylococcus medium No. 110. These studies did not give conclusive indications as to the superiority of any one medium. It should be noted that except for tellurite glycine agar, the media used by Jay (1963) and Crisley et aï. (1965) were different. De Waart et al. (I968) compared the efficiency of Baird-Parker's egg-tellurite-glycine-pyruvate-agar and Chapman's agar in the enumeration of S. aureus in foods. They concluded that the former medium was better, A new medium, phenolphthalein diphosphate agar with polymyxin was found to give results comparable to seven other selective media (staphylo coccus medium Mo. 110, tellurite-polymyxin-egg-yolk agar, Baird-Parker medium, Vogel and Johnson agar, egg yolk-sodium azide-agar, Russian milk-salt-agar, and English milk-saltagar) when tested for the Isolation and enumeration of coagulase-positive staphylococci from foods (Hobbs et , I968). Liquid enrichment media have also been used in conjunction with the solid plating media for greater recovery of staphylo cocci especially when small numbers are involved. Wilson et al. (1959) incubated aliquots of food samples (custard, ham, creamed chicken, and milk) in an enrichment broth (3«7^ brain heart infusion broth, 2.0^ mannitol, and 7.5^ NaCl) for 24-48
