OBJECTIVE: The purpose of the present study was to determine the prevalence and
molecular epidemiology of extended-spectrum beta-lactamase (ESBL)-producing …

Objectives To establish the molecular epidemiology and antimicrobial resistance pattern of
extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae harbouring bla CTX …

Introduction Escherichia coli producing extended spectrum-β-lactamases (ESBL),
particularly CTX-M type ESBLs, have rapidly spread worldwide and pose a serious threat for …

ABSTRACT CTX-M-type extended-spectrum β-lactamases (ESBLs) have become
increasingly common worldwide, with the notable exception of the United States, where TEM …

One hundred extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae were
recovered from the intensive care unit and the urology ward of the University Hospital of …

Extended-spectrum β-lactamase (ESBL)-producing Gram-negative pathogens are a major
cause of resistance to expanded-spectrum β-lactam antibiotics. Since their discovery in the …

ABSTRACT In 2010 the Clinical and Laboratory Standards Institute (CLSI) lowered the
susceptibility breakpoints of some cephalosporins and aztreonam for Enterobacteriaceae …

Over the past 20 years, some Enterobacteriaceae mainly Escherichia coli, Klebsiella
pneumoniae, and Proteus mirabilis have demonstrated acquisition of plasmids secreting …
