Why is it important to use fresh cultures in a coagulase test?
Using fresh cultures in a coagulase test is important to obtain accurate results. The presence of viable and active bacteria in a fresh culture ensures that the enzyme coagulase is active and able to induce clotting of plasma, which is necessary for a positive test result. Using old or expired cultures may lead to false negative results due to decreased enzyme activity.
