[Prevalence and risk factors of methicillin-resistant Staphylococcus aureus colonization among residents living in long-term care facilities in southern Spain].

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) has become the most important problem related to multiresistant microorganisms in the health care system. Long-term-care facilities (LTCFs) are one of the main reservoirs of this microorganism. The objective of our study was to determine the prevalence and factors associated with MRSA colonization among subjects living in LTCFs in southern Spain.
