Abstract

Staphylococcus aureus is a frequent cause of community and hospital acquired infections. One of the important sources of Staphylococcus for nosocomial infection is nasal carriage among hospital personnel. Emergence of drug resistance strains especially Methicillin resistant Staphylococcus aureus is a serious problem in hospital environment. This study aimed to determine the nasal carriage rate of Staphylococcus aureus with special reference to MRSA among healthcare workers at rural teaching hospital in Medchal, Telangana. We screened 100 healthcare workers of various clinical departments of MediCiti Institute of Medical Sciences. Nasal swabs taken from them were inoculated onto Blood Agar & Mannitol Salt Agar within 1 hour and incubated aerobically at 37°C for 24–48 hours. β-haemolytic colonies & Mannitol fermenting colonies which showed gram positive cocci in clusters in gram staining and produced Catalase & Coagulase were identified as S. aureus. Antibiotic susceptibility test was performed by Kirby-Bauer disc diffusion method. Methicillin resistance was detected using Cefoxitin disc diffusion method. Out of 100 healthcare workers, 26 were nasal carriers of S. aureus and among them 12 were carriers of MRSA. Overall nasal carriage rate of MRSA was 12%. Highest MRSA nasal carriage was detected among housekeeping personnel. The high rate of nasal MRSA carriage among healthcare workers found in this study necessitates improved infection control measures to be employed to prevent MRSA transmission in our hospital setting through periodic surveillance.
