Staphylococcus aureus is a ubiquitous pathogen that is the leading cause of bacterial infections worldwide, according to data published by Diekema and colleagues in 2001. Methicillin-resistant Staphylococcus aureus (MRSA) emerged in the early 1960s and was originally regarded as a nosocomial pathogen. This notion has evolved dramatically over the last 2 decades and community-associated (CA-MRSA) has now become a chief public health concern in the United States.
