Recently, the emergence and rapid dissemination of extended-spectrum beta-lactamase
(ESBL)-producing bacteria, particularly of the family Enterobacteriaceae, has posed serious …

Background Extended-spectrum β-lactamases (ESBLs) in Gram-negative organisms is now
a major concern in Enterobacteriaceae worldwide. This study determined a point …

A study was designed to characterize 22 nonrepeat extended-spectrum β-lactamase (ESBL)–
producing Escherichia coli clinical isolates recovered from specimens originating from …

Background The prevalence of extended-spectrum β-lactamase-producing Escherichia coli
(ESBL-EC) has increased recently. The aim of this study was to further characterise and to …

Background The emergence of extended-spectrum beta-lactamase (ESBL)-producing
isolates has important clinical and therapeutic implications. High prevalence of ESBL …

Purpose Here, we investigated the genetic relationships and characteristics of extended-
spectrum beta-lactamase-producing Escherichia coli (ESBL-E. coli) isolates from healthy …

Introduction. Infections due to extended spectrum β‐lactamase producing
Enterobacteriaceae are on the rise. They pose serious public health problems due to their …

Objectives: The aim of this prospective study was to assess the extent of dissemination of
extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae at the hospital level …

Purpose: Extended-spectrum β-lactamases (ESBLs) have become an issue in community
worldwide due to an increase in antibiotic resistance over the past decade. This study was …

Introduction: Few reports about the prevalence and genetic basis of extended spectrum beta-
lactamases (ESBLs) are available from Saudi Arabia. We sought to determine the …
