چکیده

Resistance of Escherichia coli to third-generation cephalosporin (3GC) in fecal samples representative of French egg production was studied. The susceptibility to cefotaxime of E. coli isolates obtained by culture on nonselective media was determined. Twenty-two nonsusceptible isolates were obtained (7.51%; 95% confidence interval, 4.49 to 10.54%), the majority of which came from young birds. Most isolates carried a blaCTX-M-1 group gene, and a few carried a blaCMY-2-like gene. Control of 3GC resistance in laying hens is needed.

Background and Aims: The rate of urinary tract infection caused by the extended-spectrum-β-lactamase- (ESBL) producing Escherichia coli (E. coli) is increasing worldwide. This study aimed to assess the frequency of blaCTX-M genes in the E. coli isolated from urinary tract infection (UTI) in outpatients. Methods: 240 E. coli bacteria were isolated from the outpatients’ urine samples in the Kerma...

Detection of TEM, SHV and CTX-M Antibiotic Resistance Genes in Escherichia coli Isolates from Infected Wounds

ABSTRACT        Background and Objective: Escherichia coli is one of the most common causes of hospital-acquired infections. Extended-spectrum β-lactamase (ESBL)-producing E. coli strains are resistant to third-generation cephalosporins. The three main genes involved in ESBL production are TEM, SHV and CTX-M. Detection of ESBL-producing E. coli is of importan...

Antibiotic Resistance Pattern and Phylogenetic Groups of the Uropathogenic Escherichia coli Isolates Recovered from the Urinary Catheters of the Hospitalized Patients

Introduction: Almost 80% of nosocomial urinary tract infections (UTIs) are due to catheterization. Catheter-associated UTI (CAUTI) is the primary source for colonization of antibiotic-resistant pathogens, and uropathogenic Escherichia coli (UPEC) is the most common causative bacteria. This study was conducted to determine the phylogenetic groups, and antibiotic resistance pattern as the two imp...
