Staphylococcus aureus is a common commensal bacterium in the nasal mucosa. Several strains have acquired resistance to methicillin (methicillin-resistant S. aureus, MRSA) and most β-lactam antibiotics; such drug resistance, in addition to the intrinsic high virulence potential of S. aureus, makes MRSA an important source of health-care-associated and community-associated infections.
