Strains of Enterobacteriaceae producing an extended spectrum β‐lactamase have become
a concern in medical bacteriology as regards both antimicrobial treatment and infection …

Extended-spectrum beta-lactamase (ESBL) production in members of the
Enterobacteriaceae can confer resistance to extended-spectrum cephalosporins …

The detection of extended-spectrum β-lactamase-producing (ESBL) bacteria is of
importance for infection control and epidemiological surveillance. We aimed to compare …

Extended-spectrum beta-lactamases (ESBLs) are a large, rapidly evolving group of
enzymes that confer resistance to oxyimino cephalosporins and monobactams and are …

Three commercially available microbiology identification and susceptibility testing systems
were compared with regard to their ability to detect extended-spectrum β-lactamase (ESBL) …

A three-phase analysis of the Vitek ESBL test and a double-disk (2 disk) test was performed
to assess their ability to detect extended-spectrum beta-lactamases (ESBLs) in members of …

Using a set of 33 well-defined extended-spectrum beta-lactamase (ESBL)-producing strains
of Escherichia coli and Klebsiella pneumoniae, we compared three screening methods for …

Production of extended-spectrum β-lactamases (ESBLs) is an important mechanism of β-
lactam resistance in Enterobacteriaceae. Identification of ESBLs based on phenotypic tests …

The three-dimensional and clavulanate double-disk potentiation tests were compared as
procedures for the detection of extended-spectrum beta-lactamase production in 32 strains …

Extended-spectrum β-lactamases (ESBLs) are plasmid-mediated bacterial enzymes that
confer resistance to a broad range of β-lactams. They are descended by genetic mutation …
