Ginosaisolateswereidentified.Alloftheseisolateswerebiofilm producers. Carbapenem resistance was detected in 40 of the isolates, and blaTEM (37/5 ), blaVIM (30 ), and blaCTX-M (20 ) have been one of the most common -lactamase genes. The highest resistance was detected to cefotaxime, ceftazidime, meropenem, imipenem and piperacillin, and 16 (40 ) isolates were resistant to these antibiotics. The minimum inhibitory concentrations (MIC) of colistin was reduce than two g/mL and no resistance was observed. Isolates were categorized to 17 MDR, 13 mono-drug resistance, and ten susceptible isolates. Higher genetic diversity was also observed among the isolates (28 ERIC kinds) and most carbapenem-resistant isolates were classified into four principal varieties. Conclusion: Antibioticresistance,particularlycarbapenemresistancewasconsiderable among the P. aeruginosa isolates colonizing burn wounds. Combining carbapenem resistance with biofilm production and virulence things would result in serious and difficult-to-treat infections.KEYWORDSDepartmentofMicrobiology,Facultyof Medicine, Zanjan University of Medical Sciences, Zanjan, Iran DepartmentofMicrobiology,Facultyof Medicine, Shahid Sadoughi University of Health-related Sciences, Yazd, Iran Clinical Microbiology Investigation Center, Ilam University of Healthcare Sciences, Ilam, Iran5 Laboratory Sciences Study Center, Golestan University of Medical Sciences, Gorgan, Iran six 4Department of Laboratory Sciences, FacultyofParamedicine,Golestan University of Medical Sciences, Gorgan, IranCorrespondence Hossein Kazemian, Division of Microbiology,FacultyofMedicine,Ilam University of Medical Sciences, Ilam, Iran.

Burn injuries destroy the skin protection against infection and disrupt the physiologic function on the immune program, and burn patients are at higher danger of acquiring hospitalassociated infections. two P. aeruginosa is definitely an aerobic Gram-negative bacilli and accounts for opportunistic or nosocomial infections in burn patients, cystic fibrosis, and immunocompromised men and women.3 Pseudomonas aeruginosa possesses a wide selection of virulence things which include elastase, exoenzymes, and exotoxin A that are regulated by cell-to-cell signaling systems. The primary virulence aspect developed by isolates of P. aeruginosa is exotoxin A which has an essential role in the pathogenesis of this microorganism.4Also, flagella and pili possess a important function as virulence aspects independently.five P. aeruginosa is able to boost the excretion of virulence determinants in the cytoplasm of target cells through a sort III secretion program. These factors are related with larger mortality, particularly in burn sufferers.6 Moreover, biofilm formation is usually a simple and important virulence aspect that improves bacterial survival in harsh circumstances for instance dryness or the presence of antiseptics.7 Biofilm also is one of the primary techniques for antibiotic resis.
