Incidence of post-operative infections and antibiotic resistance trends: A clinical study

Gram-negative organisms, particularly Escherichia coli and Klebsiella species, are predominant pathogens. Therefore, it is of interest to evaluate the microbiological culture reports, antimicrobial susceptibility testing and clinical records of surgical patients who developed post-operative infections. In our study 200 surgical patients were included, among 32 developed post-operative infections, so giving an overall infection incidence of 16%. High resistance rates were observed against commonly prescribed antibiotics including amoxicillin-clavulanate and ceftriaxone, whereas lower resistance was noted for carbapenems. Thus, data shows the increasing burden of antimicrobial resistance in post-operative infections and the importance of continuous microbiological surveillance for effective infection control.
