Resistance pattern of mupirocin in methicillin-resistant Staphylococcus aureus in trauma patients and comparison between disc diffusion and E-test for better detection of resistance in low resource countries.

Introduction: Mupirocin is an effective antibiotic for elimination of methicillin-resistant Staphylococcus aureus (MRSA) from nasal colonization and has been used to control outbreaks. Current reports show an increasing trend of resistance to this antibiotic.

Objective: This study was conducted to analyze the resistance pattern of MRSA to mupirocin among the patients admitted following trauma to an apex trauma care center of India and to compare the efficacy between two methods of antimicrobial sensitivity testing.
