Coagulase Test | Theory & Results in Tubes and on Slides

The video tutorial explains the coagulase test used in microbiology to differentiate between Staphylococcus aureus and Staphylococcus epidermis. It begins with an overview of the two species and the role of the coagulase enzyme. The normal clotting process in the human body is described, highlighting how coagulase can bypass these mechanisms, leading to potential health risks like embolism. The tutorial then details how to perform the coagulase test both in a test tube and on a microscope slide, explaining how to interpret the results for coagulase-positive and coagulase-negative organisms.
