Identification of positive blood cultures should prompt initiation of empiric therapy as well as further clinical evaluation.

  2. 22 Ιουλ 2023 · Biochemical Tests: Tests to identify specific metabolic characteristics of Staphylococcus aureus, including the catalase test (positive) and coagulase test (positive). Molecular Tests : PCR and genetic testing to detect specific genes, including those related to antibiotic resistance like mecA gene in MRSA.

  3. Other infections require samples of blood or infected fluids, which are sent to a laboratory to grow (culture), identify, and test the bacteria. Laboratory results confirm the diagnosis and determine which antibiotics can kill the staphylococci (called susceptibility testing).
