Clinical Significance
Methicillin-resistant Staph. aureus (MRSA) is a major cause of healthcare associated infections and is commonly found in the nose or on skin of healthy individuals. Early screening of patients for MRSA nasal carriage to identify those patients that require isolation can be a part of an effective infection control program.
