Abstract
Surgical site infections are one of the most important causes of health care associated infections in surgical patients. Prevalence of surgical site infections varies between 5%-24% in India. Staphylococcus aureus is one of the most important organisms causing surgical site infections. Treatment of MRSA infections are challenging, because of the restricted availability of antimicrobials of proven efficacy. In this study a total of 242 pus Samples were received over a periodfrom January 2018 to December 2018,212(87.6%) samples were culture positive showing growth of aerobic bacteria , among these 212positive samples, males were 141 and females were71.The most Common organism isolated was Staphylococcus aureus with 75(35.3%) isolates ,of these75 Staphylococcus aureus isolates, 21 (28.0%)isolates were methicillin resistant Staphylococcus aureus. In antibiotic susceptibility patterns, MRSA isolates were highly susceptible to linezolid, clindamycin, gentamicin, chloramphenicol tetracycline and highly resistant to penicillin, cefoxitin, erythromycin, cotrimoxazole, ciprofloxacin, tetracycline, gentamicin, chloramphenicol.
