Baird-Parker Agar
BK055GC
CAD$969.70
Baird-Parker Agar with egg yolk and potassium tellurite is a selective medium for the detection and enumeration of coagulase-positive staphylococci (Staphylococcus aureus and other species) in animal origin biological samples, pharmaceutical products, cosmetics, foods and water.
Available as dehydrated base medium (without egg yolk or tellurite) : 500g or 5Kg containers available.
To be used with Egg Yolk emulsion with Potassium Tellurite (BS06008)
In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone, an animal byproduct.
The growth of staphylococci is favored by sodium pyruvate and glycine. Accompanying microflora is inhibited by lithium chloride and potassium tellurite (added extemporaneously), as well as a high concentration of glycine.
The addition of sulfamethazine (optional) after autoclaving inhibits most Proteus and thus limits the invasion of the medium by this species.
Enrichment with egg yolk aids in identification by showing the action of lecithinase. Staphylococcus aureus presents black or grey colonies (due to the reduction of tellurite to telluride), surrounded by clearing zones in the cloudy egg yolk medium.
In principle, other microorganisms are inhibited. However, it is possible to observe brown or greenish micrococci, white yeast colonies or brown Bacillus or Proteus.
