A study on the aac-(6)-lb-cr gene prevalence among ciprofloxacin-resistant strains of uropathogenic .

Introduction: Urinary tract infections (UTIs) are very common. Indiscriminate use of antibiotics has led to the development of resistance to most of the commonly used antibiotics including quinolones.

Aim: This study aimed to find out the prevalence of ciprofloxacin resistance among the uropathogenic , to determine the virulence factors of these isolates, and to detect the aac-(6)-lb-cr gene among those isolates with minimal inhibitory concentrations (MICs) of ciprofloxacin >256 mcg/ml.
