Baird-Parker Agar Medium is a selective and differential medium specifically designed for the isolation and identification of coagulase-positive staphylococci, particularly Staphylococcus aureus. It is widely used in clinical, food, and environmental microbiology laboratories due to its high selectivity and ability to differentiate between different types of staphylococci based on colony morphology.

1. The medium is highly selective, containing lithium chloride and potassium tellurite, which inhibit the growth of non-staphylococcal microorganisms, allowing for the specific growth of staphylococci.
2. The composition includes tryptone, beef extract, and yeast extract, which provide essential nutrients for bacterial growth, while sodium pyruvate and glycine stimulate the growth of staphylococci.
3. The medium differentiates coagulase-positive staphylococci by producing black colonies due to the reduction of potassium tellurite, and the presence of egg yolk allows for the detection of lipase and lecithinase activity, resulting in clear zones around the colonies.

Baird-Parker Agar Medium, also known as BPA Medium, is a specialized agar used in microbiology for the selective cultivation and differentiation of coagulase-positive staphylococci. Its unique composition and selective properties make it an essential tool in clinical and food microbiology laboratories.

The Baird-Parker Agar Medium is designed for the selective cultivation and differentiation of coagulase-positive staphylococci, particularly Staphylococcus aureus. It offers high selectivity and clear differentiation based on colony morphology.
