Laboratory methods for identification of S. aureus

Laboratory methods to identify Staphylococcus aureus typically involve taking a sample from a patient (like blood, wound, or nasal swab) and growing it on special nutrient plates. If the bacteria grow, they are then tested for specific traits, such as producing a golden pigment, which is characteristic of S. aureus. Additional tests may include observing the bacteria under a microscope, conducting biochemical tests to see how they react with certain chemicals, or using more advanced techniques like DNA analysis to confirm their identity. These methods help accurately detect S. aureus to guide appropriate treatment.
