Detection of plasmid-mediated qnr genes among the quinolone-resistant Escherichia coli isolates in Iran.
INTRODUCTION Plasmid-mediated quinolone resistance, which complicates treatment, has been increasingly identified in Escherichia coli isolates worldwide. The purpose of this study was to identify the plasmid-mediated qnrA and qnrB genes among the quinolone-resistant Escherichia coli isolated from urinary tract infections in Iran. METHODOLOGY A total of 140 Escherichia coli isolates were colle...
متن کاملThe Prevalence of Plasmid-mediated Quinolone Resistance Genes in Escherichia coli Isolated from Hospital Wastewater Sources in Tehran, Iran
BACKGROUND Considering the importance of hospital wastewaters as potential reservoirs for the dissemination of bacterial pathogens such as Escherichia coli and antibiotic resistance genes in the environment, the need for such information becomes imperative. METHODS E. coli strains were isolated from hospital wastewater sources in Tehran, Iran, over a 24-month sampling period (Jun 2014- Jun 20...
متن کاملPlasmid-Mediated Quinolone-Resistance (qnr) Genes in Clinical Isolates of Escherichia coli Collected from Several Hospitals of Qazvin and Zanjan Provinces, Iran
OBJECTIVES Escherichia coli is regarded as the most important etiological agent of urinary tract infections. Fluoroquinolones are routinely used in the treatment of these infections; however, in recent years, a growing rate of resistance to these drugs has been reported globally. The aims of this study were to detect plasmid-mediated qnrA, qnrB, and qnrS genes among the quinolone-nonsusceptible...

strain with no parC mutations. This is consistent with previous findings that gyrA mutations are necessary for quinolone resistance, whereas parC mutations appear to be complementary, as resistant strains do not carry parC mutations alone. – 6 Some studies further suggest that additional parC mutations facilitate increasing levels of resistance, but our study did not support this. For example, ...
متن کاملفراوانی ژن‌های پلاسمیدی qnrA، qnrB و qnrS و تعیین حساسیت آنتی بیوتیکی در ایزوله‌های اشرشیاکلی مقاوم به کینولون و فلوروکینولون جدا شده از نمونه‌های بالینی کرمان
Background: Plasmid-mediated quinolone resistance, which complicates treatment, has been increasingly identified in Escherichia coli isolates worldwide. The purpose of this study was to investigate the frequency of plasmid-mediated qnrA, qnrB, and qnrS genes among quinolones resistant E.coli isolated from Kerman hospitals, Iran. Methods: In the current study, 80 E. coli isolates...
