Selective isolation of coagulase positive Staphylococci in food.
Baird-Parker modified the Tellurite Glycine Medium of Zebovitz, Evans and Niven. It is recommended for microbial limit tests by the USP. Potassium Tellurite and Lithium Chloride selectively suppresses the growth of most bacteria but allows the growth of Staphylococcus aureus. The addition of pyruvate and glycine enhances the growth of Staphylococci. The differentiation of coagulase-positive staphylococci is noted by the reduction of Potassium Tellurite which results in a black colony. Staphylococcus that contain lecithinase break down the egg yolk and cause a clear zone. An opaque zone may be formed due to lipase activity.
