Baird Parker Agar Culture Media

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.

Small volumes of Baird Parker Agar culture media vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
