RPF AGAR BASE (ISO 6888-2:1999)

Description

Rabbit Plasma Fibrinogen Agar Base works on same principle as Baird Parker Agar with addition of Fibrinogen Plasma together with Trypsin and Potassium Tellurite as single supplement. Baird Parker Agar was developed by Baird Parker from the Tellurite-glycine formulation of Zebovitz et al for isolation and enumeration of Staphylococci in food and other material since it allows a good differentiation of coagulase positive strains. The composition laid down is as per ISO 6888-1. Studies show that almost 100% of coagulase positive Staphylococci are capable of reducing tellurite, which produces black colonies, whereas other Staphylococci cannot always do so. Smith and Baird-Parker found that the addition of 50 mg/l Sulphamethazine suppresses the growth and swarming of Proteus species.
