Detection of Integron Genes Responsible for Antibiotic Resistance InPseudomonas Aeruginosa Isolated from Urinary Tract Infections of Patients Admitted to High Risk Wards of Hospitals of Tabriz

خلاصه انگلیسی

Background & Objectives: Pseudomonas aeruginosa is one of the most important causative agents among hospital acquired infections, especially in ICU and burn units.The organism is known to be inherently resistance to a wide variety of antimicrobials. Integrons have been recognized as important contributor to the acquisition and dissemination of antibiotic resistance gene in Gram-negative bacteria. Investigate the resistance profiles of Pseudomonas aeruginosa isolated from urine of patient with Urinary Tract Infections (UTI) to 13 antibiotics, and its relation to presence of various class of integrons. Methods: In total , 65 clinical P. aeruginosa were isolated from urine of patients with UTI over a period of 10 months. All clinical samples were initially identified with standard phenotypic methods and then studied for their resistance pattern toward 13 antibiotics by disc diffusion methods according to CLSI recommndations. Presence of Class 1, 2 and 3 integrons was assessed by performing PCR. Results: The resistance rate were between 23,6% for meropenem and 100% for rifampicin. PCR results showed that 36 (55.38 %) of P. aeruginosa isolates carried class 1 integron. None of the isolates detected class 2 and3 integron genes. The amplicon size of integron 1 was 457 bp. Resistance towards antibiotics associated with the presence of Class 1 integron by PCR. Class 1 integron was found in 29 strains revealing resistance to ceftriaxone , rifampicinand 20strain revealing cefepime , ceftazidime , carbenicillin and 19 resistance to ampicillin/sulbactam respectively. Conclusion: Our study indicate that Class 1 integrons are widespread in P. aeruginosa isolated from clinical samples of University teaching hospitals of Tabriz. The antibiotic resistance rates in class 1 integron-positive strains of P. aeruginosa were noticeably higher than those in class 1 integron-negative strains.
