Frequency and Antibiotic Resistance Patterns of Isolated Bacteria from Burn Wounds Infections in Imam Khomeini Medical Center in Urmia

Abstract

Background & Aims: Wound infection is a major challenge in burn care and is the most common cause of death from burn. Knowledge of the major organisms that are commonly encountered in each unit is essential for effective treatment of infections. The aim of this study was to determine the type of bacterial infections in burn wounds and evaluate the frequency and antibiotic resistance of bacteria isolated from the burn section. Materials & Methods: This descriptive study involved 120 burn patients from Imam Khomeini Hospital in Urmia, who were randomly selected from the hospital’s database. We obtained samples from their burn wounds and performed conventional biochemical tests to identify the strains. We applied the disk diffusion method to determine the antibiotic resistance pattern. We used SPSS version 26 for the statistical analysis. Results: In this study, Acinetobacter baumannii was the most common organism in the burn section. Staphylococcus aureus, Pseudomonas aeruginosa, Coagulase-negative staphylococci, Acinetobacter lwoffi, Escherichia coli, Enterobacter species, and Klebsiella pneumoniae were next in line. According to the antibiogram, %67.7 of the strains had Multiple Drug Resistance. Also, 42.3% of Methicillin-Resistant Staphylococcal isolates were identified. Conclusion: The high frequency of Multidrug-Resistant strains in the burn ward is a serious warning in the treatment of burn wound infections in this hospital. Therefore, it seems necessary to develop new treatment strategies and follow the correct health and treatment protocols.
