molecular analysis of pseudomonas aeruginosa strains isolated from burn patients by repetitive extragenic palindromic-pcr (rep-pcr)

conclusions according to the findings of our study, there were diverse and high-level resistant p. aeruginosa strains in the major burn center in khuzestan. therefore, we faced troubles controlling the diverse p. aeruginosa clones in the burn patients. methods in a cross sectional study, a total of 75 strains of p. aeruginosa were isolated from burn patients at taleghani hospital, which is the main burn center in ahvaz, iran, during may- september, 2015. antimicrobial susceptibility of the isolates was detected using the disk diffusion method. genetic relatedness of the isolates was analyzed by the rep-pcr technique. background infections caused by pseudomonas aeruginosa raise an important issue in burn patients. molecular epidemiologic studies have been used for investigating the genetic features of p. aeruginosa and rep-pcr technique has been introduced as a rapid low cost method. results antimicrobial susceptibility testing showed more than 80% of p. aeruginosa isolates were resistant to ceftriaxone, cefotaxime, meropenem, piperacillin/tazobactam, ticarcillin, ciprofloxacin, and amikacin. based on the rep-pcr analysis, 20 different common types and 20 unique patterns were illustrated among p. aeruginosa isolates. objectives this study focused on investigating the genetic similarity and antibiotic resistance pattern of p. aeruginosa isolated from the clinical samples of burn patients in a major burn center in khuzestan province, iran.
