Prevalence and antimicrobial susceptibility pattern of methicillin resistant Staphylococcus aureus (MRSA) in a tertiary care hospital, India.

Abstract :

Background: Methicillin resistant Staphylococcus aureus (MRSA) strains are usually resistant to several antibiotics and also intrinsically resistant to β–lactam antibiotics and have particular ability to spread in hospitals. Such multi drug resistant MRSA has become a major cause of nosocomial and community acquired infections. Therefore the knowledge of current trends of MRSA and their antimicrobial profile is necessary. Material and methods: All S.aureus isolates obtained during the study period were included in the study. Routine antimicrobial susceptibility testing was performed and interpreted as per standard guidelines. Methicillin resistance was detected using cefoxitin disc diffusion method. Results: A total of 167 (36.78%) strains of S.aureus were found to be methicillin resistant. Multi drug resistance was observed in 26.9% of MRSA strains. However, no strain was resistant to vancomycin and linezolid. Conclusion: Strict implementation of infection control measures and robust antimicrobial stewardship are required to prevent spread and reduce emergence of MRSA in medical care facilities.
