Hence, the focus of medical care should be preventing infections and resistant isolates. The current study investigates the prevalence of infectious agents and antimicrobial resistance patterns during three years.Materials and Methods: A total of 960 isolates were collected from different sample kinds cultured for 615 burn patients who were hospitalized during January 2016 to December 2018 in Amir-Al-Momenin Burn Center. The type of microorganism and their antibiotic resistance patterns were identified by microbiological tests and the standard disk-diffusion method according to the introduced standard techniques.Results: Incidence of positive growth was seen more in males than in females. Most of the burns encountered were due to flame injuries (35.4%). Based on the diversity of bacterial isolates, Pseudomonas aeruginosa was the most frequent pathogen (49.9%), followed by Klebsiella sp. (9.7%), Acinetobacter sp. (7.2%) and Staphylococcus aureus (6.5%). The trend of resistance of meropenem was declining in P. aeruginosa isolates. Klebsiella sp. as the second most prevalent agent showed a high level of resistance to the studied antibiotics. The antibiogram results for S. aureus isolates showed an increasing trend in MRSA isolates.Conclusion: By evaluating the infectious agent, it was found that although frequencies of microorganisms and resistant isolates were a little high, performing a multidisciplinary approach controls the trend during the study period. These achievements have been gained due to a strict politicized infection control and stewardship program in the appointed burn center.Keywords: nosocomial infections, antibiotic resistance pattern, burn
