    Abstract:
    Several biochemical tests were studied to determine their correlation with coagulase activity. The lysozyme test was in perfect agreement with the coagulase test for the strains studied. Mannitol fermentation and egg yolk lipase tests were in agreement with the coagulase test for 96% of the coagulase positive strains. Sheep red...

    Abstract:
    The need for better procedures for detecting Staphylococcus aureus prompted an investigation to improve coagulase testing. The rates of coagulase clotting were studied by using varying concentrations of trypsin inhibitor and coagulase-reacting factor (CRF). Egg white trypsin inhibitor activated coagulase clotting when added to a final concentration between 2 and...
