Bacteriological profile of surgical site infections and their antimicrobial susceptibility pattern at a tertiary care hospital, Western Gujarat

Abstract

Surgical site infection (SSI) is a frequently occurring repercussion of surgery. It results in mortality and morbidity post-surgery. The present study aims to isolate the organisms causing SSI and determine the antimicrobial susceptibility patterns of the isolates.A total of 250 patient samples were included in the study, their demographic details obtained and processed as per Standard Microbiological Protocols. Antibiotic susceptibity of the positive cultures was performed using Modified Kirby-Bauer disc diffusion method. Out of the 250 samples, 102 (40.8%) samples showed positive culture growth. Positivity rates were higher in male patients (43.88%). The most prevalent Gram-negative isolate was (23.53 %), followed by (20.59%) and others. The only Gram-positive isolate was (21.57%). Most of the Gram-negative isolates were sensitive to imipenem, meropenem, ertapenem, ceftazidime-avibactam and aztreonam. Most of the gram-positive isolates were sensitive to linezolid and levofloxacin. The current analysis found that was the most often related bacteria to SSI, followed by , , and other infections. Periodic analysis of the causative organisms and their antimicrobial susceptibility pattern is necessary to confine the burden of SSI.
