TPEY AGAR BASE

Tellurite Polymyxin Egg Yolk Agar was formulated by Crisley et al for the detection and enumeration of coagulase-positive Staphylococci in food materials. It is also used for the recovery of coagulase-positive Staphylococci from foods, air, dust and soil. The base must be supplemented with potassium tellurite solution and enriched with an egg yolk emulsion prior to its use for the isolation of Staphylococci. Coagulase-negative Staphylococci and other organisms are greatly suppressed on this medium.
