Extended-Spectrum Beta-Lactamases [PDF]

Canadian Journal of Infectious Diseases and Medical Microbiology, 2006
The definition of extended-spectrum beta-lactamases (ESBLs) has expanded rapidly, in terms of both the number and the variety of enzymes. Bacteria bearing plasmidic ESBLs are spreading widely throughout the world.

Dissemination of IncF plasmids carrying beta-lactamase genes in Gram-negative bacteria from Nigerian hospitals

Journal of Infection in Developing Countries, 2013
Introduction: Production of beta-lactamases is the predominant cause of resistance to beta-lactam antibiotics in Gram-negative bacteria. We investigated the diversity of plasmid-borne beta-lactamase genes and replicon type of the plasmids carrying the ...

Multiparametric determination of genes and their point mutations for identification of beta-lactamases [PDF]

, 2010
More than half of all currently used antibiotics belong to the beta-lactam group, but their clinical effectiveness is severely limited by antibiotic resistance of microorganisms that are the causative agents of infectious diseases. Several mechanisms for

Simple disk-based method for detection of Klebsiella pneumoniae carbapenemase-type beta-lactamase by use of a boronic acid compound [PDF]

, 2008
A disk potentiation method using carbapenems as substrates and 3-aminophenyl boronic acid as an inhibitor was evaluated for the detection of Klebsiella pneumoniae carbapenemase (KPC)-type beta-lactamases. When combined with nonsusceptibility to ertapenem,

Cefotaxime/sulbactam: clinical and pharmacological characteristics [PDF]

Клиническая микробиология и антимикробная химиотерапия, 2019
The recently approved cefotaxime/sulbactam, combination of third-generation cephalosporin (cefotaxime) and beta-lactamase inhibitor (sulbactam), can combat resistance mechanisms associated with the production of serine beta-lactamases, including some ...

Evaluation of the ESBL-coding plasmids transmissibility in E. coli isolated from ambulatory patient's urina [PDF]

, 2018
Representatives of the Enterobacteriaceae family are the main causative agents of urinary tract infections. Escherichia coli can exhibit resistance to [beta] -lactam antibiotics by synthesizing ESBL (extended spectrum [beta]-lactamases).

Extended-spectrum Beta-lactamase and AmpC beta-lactamases producing gram negative bacilli isolated from clinical specimens at International Clinical Laboratories, Addis Ababa, Ethiopia.

PLoS ONE, 2020
BackgroundExtended spectrum Beta-lactamases (ESBLs) and AmpC beta-lactamases (AmpC) are the common enzymes produced by gram negative bacilli, which are their main mechanisms of resistance to all generations of cephalosporins.
