Prevalence of Nasal colonization with Staphylococcus aureus in 4 cities in Peru

Abstract

The increasing prevalence of methicillin-resistant Staphylococcus aureus is a global problem, affecting military and non-military populations around the world. MRSA was first documented in 1960, and until the late 1990s, its presence was confined largely to hospital settings with occasional outbreaks. Since then, the number of outbreaks and infections caused by MRSA, specifically community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) strains increased steadily [1, 2]. USA300 genotype is the predominant CA-MRSA strain recovered from outbreak investigations in U.S. and different countries in Europe and Asia, such as Japan [3], constituting a common cause of community associated skin and soft tissue infections (SSTIs).
