چکیده
Background: To evaluate the drug susceptibility profiles and the frequency of beta-lactamase encoding genes in Pseudomonas aeruginosa (P. aeruginosa) obtained from burn patients. Methods: Totally 93 non-duplicate clinical isolates of P. aeruginosa were recovered from burn patients of Taleghani Burn Hospital of Ahvaz. Antibiotic susceptibility testing was conducted by disk diffusion method according to the CLSI 2017 recommendations. PCR assay was performed by to find beta-lactamase encoding genes.Finding: In this study, most clinical specimen was obtained via wound swabs [65 (69.9%)], followed by blood [14 (15.1%)] and biopsy [7 (7.5%)]. Forty-two (45.16%) patients were maleand 51(54.84%) were female. High resistance was observed for most of antibiotics especially for gentamicin and ciprofloxacin (Up to 85%), whereas the highest susceptibility was reported for colistin (100.0%), followed by ceftazidime (66.7%). According to PCR results, 16.1% (15), 9.7% (9) and 14.0% (13) of isolates carried blaDHA, blaVEB and blaGES genes, respectively. It also revealed that the blaVEB gene was found to coexist within 2 isolates (2.2%). Conclusion: Antibacterial resistance is high among P. aeruginosa isolates. Colistin is highly active against multi-drug resistant P. aeruginosa isolates. Antimicrobial susceptibility testing can confine indiscriminate uses of antibiotics and resistance increase, and can improve management of treatment.کلیدواژه ها
