which media is use to do the coagulase test?
COAGULASE TEST:
Coagulase test is used to differentiate Staphylococcus aureus (positive) from Coagulase Negative Staphylococcus (CONS).
Coagulase is an enzyme produced by S. aureus that converts (soluble) fibrinogen in plasma to (insoluble) fibrin.
Once you inoculate the rabbit plasma containing media for the coagulase test, how long do you wait to read the sample result?
What is the catalase test? Coagulase test? What does it mean to be: Catalase + Catalase - Coagulase + Coagulase - When working with an unknown that may be Staphylococcus (but you are not sure), how can the two tests help? Give step by step detail of how to determine you are dealing with Staphylococcus and not an organism such as Streptococcus (next week topic). Give step by step details on how to determine you are dealing with: S. epidermidis...

Would a catalase positive test always signify the presence of Staphylococci spp.? 3. What is the medical significance of a coagulase positive test result?
