Prevalence of AmpC beta-lactamase and extended spectrum betalactamase co-producer in Escherichia coli and Klebsiella species in a teaching hospitalTING, Siau Mei ValerieISMAIL, ZalinaHANAFIAH, AlfizahMalaysian Journal of Pathology
The first beta-lactamase enzyme was identified against penicillin and after that various beta-lactamases have emerged due to intensive use of antibiotics, and, therefore, they need to be classified.1 Beta-lactamases are also divided into four groups according to their biochemical properties and substr...
Extended-spectrum β-lactamase (ESBL), plasmid-mediated AmpC-β-lactamase and carbapenemase-producing Escherichia coli and Klebsiella pneumoniae have spread into the environment worldwide posing a potential public health threat. However, the prevalence data for low- and middle-income countries are still...

Production of AmpC and extended spectrum beta-lactamases among urinary isolates has created a serious problem to the successful management of the urinary tract infection. The main purpose of this study was to determine the rates of the extended spectrum beta-lactamase (ESBL) production and AmpC ...
They were then screened for the p-lactamase production, statistical analysis was done by using Chi square test. A total of 596 MDR isolates, 503 (84.39%)were beta- lactamase producers from which 306 (51.34%) were AmpC producers, followed by 118 (31.54%) ESBL producers and 115 (19.29%) ...
The AmpC β-lactamase-producer isolates were studied by employing cefoxitin disk diffusion test, AmpC induction test, AmpC cefoxitin-EDTA test, and boronic acid disk test. Our results showed that of 46 (18.4%) cefoxitin-insensitive E. coli isolates, 10 (21.7%) were positive for AmpC β-...
