PREVALENCE AND ANTIMICROBIAL SUSCEPTIBILITY PATTERN OF METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS ISOLATED AT A TERTIARY CARE INSTITUTE IN NORTH WEST REGION OF RAJASTHAN

Abstract

The emergence of Methicillin-resistant Staphylococcus aureus (MRSA) has posed a serious therapeutic challenge. We report the prevalence and antibiotic susceptibility pattern of MRSA in the hospitals attached to SPMC, Bikaner . A total of 300 staphylococcus aureus strains were been taken for study from various clinical specimens like pus, blood, sputum, throat swab, ear swab, high vaginal swab, CSF, urine, pleural fluid, semen, bile, corneal swab, etc. Routine antibiotic susceptibility testing was performed and interpreted as per standard guidelines. Methicillin resistance was detected using oxacillin disc and oxacillin screen agar method. A total of 107 (35.67%) strains were found to be Methicillin resistant. However, no strain was resistant to vancomycin. Regular surveillance of hospital-associated infection and monitoring of antibiotic sensitivity pattern is required to reduce MRSA prevalence.
