Prevalence of pathogenic microbes in post operative wound infections in various surgical specialities

The prevalence of post operative wound infections and its antimicrobial resistance pattern may vary from region to region and was included in this study. A battery of 108 post operative wound cases were included thereby various potential bacterial pathogens isolated from 94 patients and 134 isolates were possibly recovered. Among them Staphylococcus aureus (29.8%) predominated, followed by Escherchia coli (14.2%), Klebsiella pneumonia (11.9%), Pseudomonas aeruginosa (3%), Proteus mirabilis (1.5%), Serratia marcescens (0.7%) and Candida albicans (0.7%). Monomicrobial and polymicrobial infection was observed in 62.8% and 37.2% patients respectively. Orthopedic surgery and Gastrointestinal surgery was associated with an increased risk of infection due to Methicillin resistant Staphylococcus aureus and Escherichia coli respectively. Precise empirical therapy, policy of reviewing prescription patterns and continuous monitoring of resistance patterns of causative agents can help in preventing and controlling the postoperative infections.
