Bacterial Strains and Antimicrobial Resistance of Wound Infection in Burn Patients

Abstract

was 43%±19% (range, 5%–65%). The average first infection developed on the 14th±11th hospitalization day (range, 3–67 days), and the mean admission duration was 42±25 days (range, 3–98 days). The average microbial growth rate was 69.8%. The most commonly isolated infectious agent was Acinetobacter baumannii, which was identified in 37.2% of all growths. In addition, ninty two point one percent of A. baumannii infections were pandrug-resistant strains and also showed resistance to carbapenems. No colistin-resistant strains were observed. Other commonly isolated bacteria included methicillin-resistant Staphylococcus aureus (21%), Pseudomonas aeruginosa (17.8%), coagulase-negative S. aureus (13.9%), Enterococcus faecalis (5%), and Escherichia coli (3.9%). All observed strains of S. aureus were methicillin-resistant (100%). Conclusion: Because there are many bacterial strains that are resistant to antimicrobials in burn patients, caution should be exercised during the a priori administration of antimicrobial treatments. The data from this study should serve as a guideline for treating wound infections in burn patients.
