Staphylococcus aureus (S. aureus) is a very common human pathogenic microorganism that can cause a variety of infectious diseases, including skin and soft tissue infections, endocarditis, osteomyelitis, bacteremia, and lethal pneumonia. About one-third of the common population is colonized with S. aureus. MRSA is a formidable pathogen known to cause high mortality & morbidity, that poses a significant threat to public health worldwide. Presence of MRSA strains, resistant to multiple antibiotics especially in hospital stay, has complicated the management of infections caused by this bacterium. The aim of this study was to shed light on the prevalence and antimicrobial sensitivity pattern of MRSA among patients in a tertiary care center located in Faridabad, Haryana. This cross-sectional observational study was conducted in the Department of Microbiology, ESIC Medical College & Hospital, a 510 bedded tertiary care teaching hospital in Faridabad, Haryana, India. All wound samples including pus, exudates, wound swab and tissue samples received for aerobic culture and antimicrobial sensitivity from various clinical departments from January 2019 to July 2019 were included in this study. A total of 747 samples were received from January 2019-July 2019. Mean age of this study population was found to be 50.7 ± 14.8 years. Out of 747 samples, 226 (30.25%) were culture positive. Among the S. aureus isolates, methicillin resistance was seen amongst 39 (58.2%). Antibiotic Susceptibility results of S. aureus showed 100% resistance to Penicillin along with 100% resistance to Fluoroquinolones in both MRSA and MSSA. High prevalence of MRSA amongst patients highlights the importance of continued surveillance and implementation of antimicrobial stewardship program to control the menace of antimicrobial resistance. Strict adherence to Infection Control practices its regular follow up to assess the effectiveness of any hospital infection control measures taken is the key.
