INTENDED USE
Hardy Diagnostics CRITERION™ TSA Blood Agar Base is used with blood for isolation of fastidious microorganisms when hemolytic reactions are important. This medium is also recommended for use in the cultivation, storage, and transportation of pure cultures of bacteria.This dehydrated culture medium is a raw material intended to be used in the making of prepared media products, which will require further processing, additional ingredients, or supplements.
SUMMARY
TSA Blood Agar Base is typically supplemented with sheep, rabbit, or horse blood, in various concentrations, to facilitate the growth of some organisms, and for the observation of hemolytic reactions. The absence of reducing sugars and carbohydrates allows the hemolysis to occur without hindrance.TSA Blood Agar Base contains digests of soybean meal and casein which provides amino acids and other nitrogenous compounds making it a nutritious medium for many microorganisms. Sodium chloride is added to maintain the osmotic equilibrium. This medium may be supplemented with blood to provide a more nutritious medium for fastidious organisms, or with antimicrobials to provide a selective medium for specific organisms out of a mixed flora sample.
