STUDY OF METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS IN POSTSURGICAL SUTURE INFECTIONS IN A TERTIARY CARE CENTRE OF NORTH INDIA.

Abstract

Introduction: MRSA has been recognised as an important nosocomial pathogen globally and is endemic in India. Its incidence varies from 25 % in 3 western part to 50 % in Southern part of India . Post operative wound infections continues to be a major source of morbidity and mortality for patients undergoing operative procures. To nd out the incidence of MRSA in post-surgic Aim and Objectives: al suture infections and to determine its susceptibility pattern by using a battery of antibiotics. Tota Material and method: l 100 pus samples were collected from surgical site infections of admitted patients applying inclusion and exclusion criteria of department of surgery and processed in department of microbiology of Darbhanga Medical College and Hospital. Isolation of MRSA is done by routine laboratory culture method by using Mannitol Salt Agar and Cefoxitin disc 30µg(Hi-media). Out of 100 samples collected from patients from 54, Result: Staph. aureus were isolated i.e., 54%. Whereas, out of 54 isolated Staph. aureus, 24 (44.4%) were MRSA, whereas it constitutes 24% of total study subjects. MRSA infected Male (62.5%) more than female (37.5%). During antibiotic sensitivity testing MRSA found sensitive against Vancomycin and Linezolid. Conclusion: This study shows that MRSA is one of the major infectant in post operative wound infection and this is worrisome as very limited antibiotic shows sensitivity against it.
