The incidence of resistance by Enterobacteriaceae to β‐lactam/β‐lactamase inhibitors
combination is increasing in Egypt. Three phenotypic techniques, comprising AmpC disk …

Methods: The study included 909 consecutive Gram-negative isolates recovered from
clinically significant specimens during June 2007-May 2008 as part of an ICMR-ESBL study …

Methods: A total of 241 nosocomial isolates of K. pneumoniae (n= 109) and E. coli (n= 132)
from six geographically distant hospitals in India were included. These were screened for …

Aims: The aim of this study was to characterize pAmpC β-lactamase producing
extraintestinal E. coli, their phylogenetic distribution, resistance pattern, treatment options …

Plasmid-mediated AmpC beta-lactamases (pAmpCs) are cephalosporinases that hydrolyze
cephamycins as well as other extended-spectrum cephalosporins and are poorly inhibited …

Between February 2005 and January 2006 in Srinagarind Hospital, Thailand, 44 from 1730
isolates (2.5%) of Escherichia coli and 8 from 982 isolates (0.8%) of Klebsiella pneumoniae …

Objective: The aim of the study was to investigate the occurrence of AmpC-type β-lactamase
producers isolated from two hospitals in Tripoli, Libya. Methods: All clinical isolates (76 K …

Background: AmpC type β-lactamases are commonly isolated from extended-spectrum
Cephalosporin-resistant Gram-negative bacteria. Also, resistance appeared in bacterial …

One of the mechanisms of Klebsiella pneumoniae and Escherichia coli resistance to β-
lactam antibiotics is the production of β-lactamase enzymes. Among these are the AmpC β …

Purpose. Enterobacteriaceae encoding plasmid-mediated AmpC (pAmpC) β-lactamases
confer resistance to the third generation cephalosporins. pAmpC association with extended …
