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...
متن کاملAntibiotic Resistance Patterns of Escherichia coli Isolated from Children in Shahid Sadoughi Hospital of Yazd
Abstract Background Growth of drug resistance is related to number of microbial characteristics, selective pressure by antibiotic use and social and technical vicissitudes that enhance the transmission of antibiotic resistant organisms. The aim of this study was to investigate antimicrobial-resistance of Escherichia coli isolated from children in Shahid Sadoughi hospital of Yazd. Material...
متن کاملAcquisition and epidemiology of antibiotic-resistant Escherichia coli in a cohort of newborn calves.
OBJECTIVES The acquisition of antibiotic-resistant commensal Escherichia coli was examined in a cohort of newborn calves. METHODS Faecal samples were collected weekly from calves over a 4 month period and screened for E. coli resistant to ampicillin, apramycin and nalidixic acid at concentrations of 16, 8 and 8 mg/L, respectively. E. coli viable counts were performed on samples from a subset ...
متن کاملDraft Genome Sequence of Escherichia coli O157:H7 ATCC 35150 and a Nalidixic Acid-Resistant Mutant Derivative
Shiga toxin-producing Escherichia coli strains, occasionally isolated from food, are of public health importance. Here, we report on the 5.30-Mbp draft genome sequence of E. coli O157:H7 EDL931 (strain ATCC 35150) and the 5.32-Mbp draft genome sequence of a nalidixic acid-resistant mutant derivative used as a distinguishable control strain in food-testing laboratories.
متن کاملEvaluation of the antibiotic resistance and prevalence of uropathogenic Escherichia coli and detection of traT gene in isolated from patients referred to Abadan hospitals during 2017-2018
Objective: Escherichia coli is one of the most important causes agents of urinary tract infection in human. Thus, identification of Escherichia coli resistance patterns seems to be necessary. traT gene has been reported variable in Escherichia coli strains isolated from urinary tract infection. Therefore, the aim of this study was to investigate the prevalence of uropathogenic Escherichia coli ...
