Antibiotic resistant β-lactamases are diverse and complex enzymes produced by most of the
Gram-negative bacteria that are mediated by number of plasmids. The impact of these …

Abstract Extended Spectrum β-lactamases (ESBLs) can confer resistance to all extended
spectrum cephalosporins, all penicillins and monobactam. Being plasmid and transposon …

Extended-spectrum β-lactamase (ESBL)–producing bacteria are emerging pathogens. They
are descended by genetic mutation from native β-lactamases found in gram negative …

Resistance to broad spectrum β lactams, mediated by extended spectrum beta lactamase
(ESβL) and AmpC βL enzymes is an increasing problem worldwide. Presence of these in …

Purpose: The present study was carried out to characterize the ESBL types and evaluated
their in vitro activity against a collection of Gram negative bacteria (GNB) from a multicentric …

Resistance to β lactam antibiotics is an increasing problem worldwide. This review
describes the classification and mechanism of action of β lactamases and the options …

Objectives: This study was conducted to determine the prevalence of multi-drug resistance
(MDR) along with Extended Spectrum β-lactamase (ESBL) and Metallo β-lactamase (MBL) …

Infections caused by ESBL producing members of the enterobacteriaceae have rapidly
increased all over the world. ESBL increase the possibility of failure of empiric antimicrobial …

Preamble: In the visage of multidrug resistance among gram negative bacilli, we look
forward to carbapenem group of drugs as empiric choice in seriously ill patients. However …

The study on ESBL in this issue was designed to estimate the magnitude of extended
spectrum beta-lactamase producers and evaluate ESBL screening method against …
