ß Lactamase (EBSL) producing organism at a tertiary care hospital in Pakistan. Methods: All …

ABSTRACT Background and Objectives: The resistance to broad spectrum β-lactams which
is mediated by the extended spectrum beta lactamase (ESBL) enzyme is an increasing …

Background Resistance to broad-spectrum beta lactams mediated by extended spectrum
beta lactamases (ESBLs) and AmpC beta lactamases (AmpC βLs) enzymes is an increasing …

Multidrug resistance and production of extended spectrum β-lactamases (ESBLs) by enteric
gram negative rods in hospitals and community continue to be a matter of scientific concern …

Abstract Background: Extended spectrum ß Lactamases (ESbL) producing Escherichia coli
(Ec) and Klebsiella pneumoniae (KP) has increased in recent years leading to limitations of …

The present study was conducted to find the preualence of Extended spectrum b Lactamase
(ESBL) producing strains of Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli …

Extended spectrum beta-lactmase (ESBL) producing organisms create a major problem for
clinical therapeutics. The frequency of ESBL producing strains among clinical isolates has …

We studied the presence of extended spectrum beta lactamases (ESBLs) in 44 clinical
isolates of Escherichia coli collected from out-patients in two university teaching hospitals in …

Abstract β-lactamases represent the most common mechanism of β-lactam resistance.
Extended spectrum β-lactamases (ESBLs) represent a major group of β-lactamses currently …
