[ 1 ] - Evaluation of Quinolone Resistance in Escherichia coli Isolates Recovered from Urine and Feces of Patients with Acute or Recurrent Urinary Tract Infection

Introduction: Antibiotic resistance, especially in Gram-negative uropathogens such as Escherichia coli, is the main barrier to treat urinary tract infection (UTI). In recent years, the dramatically increased resistance of E. coli to quinolones, a group of widely used antibiotics, has become a significant concern. Methods: In this descriptive cross-sectional study, we collected 261 E. coli isola...

[ 2 ] - Detection of Efflux Pump Using Ethidium Bromide-Agar Cartwheel Method in Acinetobacter baumannii Clinical Isolates

Introduction: In the past decade, multidrug-resistant Acinetobacter baumannii has become one of the most critical challenges in treating infected patients. The AdeABC efflux pump is the most important among the various resistance mechanisms. This pump can force various antibiotics and ethidium bromide out of the bacterial cell to the surrounding environment. Methods: In this study, nine A. baum...
