Introduction: Burn is a devastating form of trauma, which according to its condition could run the risk of infections. Infection of wound is a major cause of morbidity and mortality in burn cases. Current study investigates the prevalence of infectious agent in three years and antibiotic resistant pattern to improve and predispose a good policy of treatment in our environment. Materials and Methods: In the present study total of 3330 samples from 713 patients were evaluated for detection of most prevalent infections and find out antibiotic susceptibility pattern with routine microbiology procedures. Results: Based on the results, 598 samples were reported positive. According to the results Pseudomonas aeruginosa, Coagulase Negative Staphylococcus and Acinetobacter sp. were the three most prevalent bacteria respectively. Furthermore based on the results of distribution and diversity of bacterial infections, wound samples were the most infected. Finally, during these three years there aren’t significant changes in resistant pattern of Gram positive and Gram negative infectious agents. Conclusion: By evaluating the infectious agents during the years of study it has been found that due to the focus on treatment of Gram negative bacteria, Gram positive bacteria especially Staphylococcus aureus and Coagulase Negative Staphylococcus are increased at least up to twofold. This increase in two important nosocomial infections is a next threat of infection and septicemia for burn victims.
