Background: Methicillin-resistant Staphylococcus aureus (MRSA) has become a major health problem worldwide. MRSA is a common pathogen implicated in Hospital-acquired infection. About 20% of patients undergoing surgery acquire at least one nosocomial infection leading to increased morbidity, mortality, hospital stay and cost of treatment. This study was designed to appraise the incidence of nasal carriage of MRSA among patients admitted for otorhinolaryngological surgical intervention in a teaching hospital. Patients and Methods: A total of 50 nasal swabs were collected from hospitalized patients at the Otorhinolaryngology Department of the University of Benin Teaching Hospital, South-South region of Nigeria during the period of three months extending from July to September 2012. Each sample was processed using standard microbiological protocols. Results: In all, 25 (50%) of the isolated organisms were Staphylococcus aureus, 6 (12%) were Staphylococcus epidermidis and 19 (38%) were Staphylococcus lugdunensis. Forty percent of the S. aureus isolated were resistant to methicillin. All the multidrug resistant strains of S. epidermidis and S. lugdunensis were also resistant to methicillin. The isolates showed resistance to the various classes of antimicrobial agents tested with the least against the aminoglycosides. Conclusion: Our results suggest that a more effective and adequate preparations such as infection control and patients selection are required to reduce the spread of multidrug resistant strains in otorhinolaryngology practice.
