Description
Baird Parker Agar Base is a selective differential medium for detecting and enumerating coagulase-positive staphylococci, particularly Staphylococcus aureus.
Lithium chloride and glycine inhibit accompanying flora. Egg-yolk tellurite supplement demonstrates lecithinase activity and produces grey-to-black colonies; rabbit-plasma fibrinogen supplement may be used for coagulase-based confirmation.
Samples are analysed by direct enumeration, MPN or RPF procedures according to the applicable part of ISO 6888. Characteristic colonies are confirmed where required.
