INTRODUCTION Community methicillin-resistant Staphylococcus aureus (CA-MRSA) has by definition a minimum inhibitory concentration for oxacillin ≥ 4mcg/mL, giving it intrinsic resistance to all beta-lactams, including cephalosporins, which is associated with the presence of the mecA gene. It also has bacteriological and epidemiological characteristics distinct from hospital-acquired MRSA, including its resistance profile to other antimicrobials, its […]
