Background and Objectives: Surgical site infection (SSI) continues to be a major healthcare-associated infection. The objective of the study was to find the bacterial profile of SSI occurring within one week of surgery and to determine their antibiotic sensitivity pattern in a tertiary care centre. Materials and Methods: Pus from the surgical sites was cultured, the organisms were identified and their antibiotic sensitivity was found by conventional methods. Data were collected to assess the risk factors. The infection rate was compared with the available standards. Results: During the one-year study period, 2472 post-operative patients were followed up, of whom 227 got infected. The infection rate was 9.2% which was high compared to the Centers for Disease Control statistics of 1.9%. The predominant isolate was Staphylococcus aureus 50 (28.2%), followed by Escherichia coli 48 (27.1%). Interpretation and Conclusion: Inpatients were studied for the first one week only because this was the optimum period for contracting infections. Moreover, majority of the patients got discharged from the hospital after one week. S. aureus was the predominant pathogen in Class I wounds, and E. coli was predominant in Class III wounds.
