چکیده مقاله :
سابقه و هدف: حضور ژن های پلاسمیدی qnr در باکتری ها عامل اصلی ایجاد مقاومت در برابر کینولون ها به شمار می آید. این مطالعه با هدف ارزیابی حضور ژن های qnr وابسته به پلاسمید و ژن های مقاوم aac(6)-Ib-cr در جدایه های بالینی اشریشیاکلی و کلبسیلا جداسازی شده از تهران انجام شد. مواد و روش ها: در این مطالعه مقطعی تعداد 132 جدایه اشریشیاکلی و 98 جدایه کلبسیلا از بیماران مبتلا به عفونت ادراری مراجعه کننده به بیمارستان آیت الله طالقانی تهران جمع آوری گردید. مقاومت آنتی بیوتیکی با استفاده از روش کربی-بائر و معیار CLSI انجام شد. پس از استخراج ژنوم، به منظور تکثیر ژن های qnr و aac(6)-Ib-cr از روش واکنش زنجیره ای پلی مراز (PCR) استفاده گردید. یافته ها: در مجموع 47.72 درصد از جدایه های اشریشیا کلی نسبت به آنتی بیوتیک سیپروفلوکساسین و 62.12 درصد نسبت به نالیدیکسیک اسید مقاوم بودند. همچنین 38.77 درصد از جدایه های کلبسیلا در برابر سیپروفلوکساسین و 51.02 درصد نسبت به نالیدیکسیک اسید مقاوم بودند. در مطالعه حاضر شیوع ژن های aac(6)-lb-cr، qnrA، qnrB وqnrS در جدایه های اشریشیا کلی به ترتیب 30.18، 37.73، 67.92 و 33.96 درصد و در کلبسیلا به ترتیب 31.42، 22.85، 68.57 و 31.42 درصد گزارش شد. نتیجه گیری: نتایج این مطالعه نشان دهنده فراوانی نسبتاً بالای ژن های qnr در جدایه های اشریشیاکلی و کلبسیلا مقاوم به سیپروفلوکساسین در شهر تهران بود.
Background & Objectives: The qnr gene is a plasmid carrying resistant genes involved in bacterial resistance to quinolone resistance plasmid factors. The aim of this study was to evaluate the presence of either gene qnr, a plasmid resistant gene, and aac (6) -Ib-cr, from Escherichia coli and Klebsiella spp isolated from clinical samples. Materials & Methods: In this sectional study, 132 E. coli and 98 Klebsiella isolates were collected from patients with the UTI referred to the ayatollah Taleghani Hospital in Tehran. Antibiotic resistance was evaluated using Kirby-Bauer and CLSI criteria. After DNA extraction, qnr and aac(6)-Ib-cr genes were amplified using PCR method. Results: In this study, E. coli strains were resistant to ciprofloxacin and nalidixic acid in a ratio of 47.72 % and 62.12 %, respectively. Also, Klebsiella isolates were resistant to ciprofloxacin and nalidixic acid in a ratio of 38.77 % and 51.02 %, respectively. In the present study, the frequency of aac(6)-lb-cr, qnrA , qnrB, qnrS genes in E. coli were 30.18, 37.73, 67.92, 33.96 %. Also these frequency were 31.42, 22.58, 68.57, 31.42 % in Klebsiella. Conclusion: This study showed high frequency of the ciprofloxacin resistant qnr gense in E. coli and Klebsiella isolates from Tehran.
