Treatment of Methicillin-Resistant Staphylococcus aureus (MRSA)

Many S. aureus infections can be treated without antibiotics by draining the wound, which should be done only by a health care professional. Before prescribing an antibiotic, a doctor must determine if MRSA bacteria are present. Accurate diagnosis is critical, because prescribing the wrong medication will delay the start of effective treatment, and it also can encourage the development of more resistant bacteria. New tests that can diagnose MRSA in a matter of hours are becoming more widely available.
