Molecular analysis and risk factors for nasal colonization with methicillin-resistant Staphylococcus aureus among community individuals attending a Family Health Care Program in Rio de Janeiro, Brazil

摘要

Background: Staphylococcus aureus has been the most prevalent pathogen in hospital infections worldwide, including Brazil. Many factors contribute to the world dissemination of hospital endemic multiresistant MRSA strains, enabling the recent emergency of Community Acquired Methicillin-Resistant S. aureus (CA-MRSA) infections. Molecular methods have been used to investigate its role in community infections to address the emergency of outbreaks of new CA-MRSA clones.
