Comparison of Verona integron-borne metallo-ß-lactamase (VIM) variants reveals differences in stability and inhibition profiles
(2016-03)
Metallo-β-lactamases (MBLs) are of increasing clinical significance; the development of clinically useful MBL inhibitors is challenged by the rapid evolution of variant MBLs. The Verona integron-borne metallo-β-lactamase ...
Characterization of novel VIM carbapenemase, VIM-38, and first detection of GES-5 carbapenem-hydrolyzing ß-lactamases in Pseudomonas aeruginosa in Turkey
(2014-03)
Pseudomonas aeruginosa isolates were collected form a Turkish hospital. Antimicrobial susceptibility was performed using the Vitek 2 Compact system, and 24 isolates were categorized as multidrug resistant (n = 18), ...
Effect of amino acid substitution in New Delhi metallo-ß-lactamase on carbapenem susceptibility
(2018-04)
The aim of this work was investigation of clinically important amino acid substitutions of NDM-1 variants. A blaNDM-1 gene was cloned into expression vector pET100/D-TOPO. The sequence of NDM-1 variants with substituted ...
Distribution of ß-lactamase genes among carbapenem-resistant Klebsiella pneumoniae strains isolated from patients in Turkey
(2015-11)
Background
The emergence of carbapenem-resistant Klebsiella pneumoniae poses a serious problem to antibiotic management. We investigated the β-lactamases in a group of carbapenem-resistant K. pneumoniae clinical isolates ...
Çoklu-İlaç Dirençli P. aeruginosa ve E. coli Suşlarında Antibiyotik Direnç Genlerinin ve Sınıf 1 İntegron Gen Kasetlerinin Araştırılması
(2018)
P. aeruginosa ve E.coli izolatlarının birçok antibiyotiğe direnç kazanması nedeniyle bu patojenlerin neden olduğu enfeksiyonların tedavisi zorlaşmıştır. Bundan dolayı klinik izolatlarda antibiyotik direnç genlerinin ...
Determination of a novel integron-located variant (blaOXA-320) of Class D ß-lactamase in Proteus mirabilis
(2014-10)
Proteus mirabilis (P. mirabilis) is one of Gram-negative pathogens encountered in clinical specimens. A clinical isolate (TRP41) of P. mirabilis was isolated from a Turkish patient in Turkey. The isolate was identified ...
Kinetic characterization of GES-22 ß-lactamase harboring the M169L clinical mutation
(2016-12)
The class A β-lactamase GES-22 has been identified in Acinetobacter baumannii isolates in Turkey, and subsequently shown to differ from GES-11 by a single substitution (M169L). Because M169 is part of the omega loop, a ...
Molecular docking analysis and determination of minimum inhibition concentration of VIM-38/R228S.
(2017)
Objective: The aim of this study was to determine the effects of residues at 228th positions of VIM-38 on minimum inhibition concentration (MIC) and molecular docking analysis. Materials and methods: blaVIM-38 gene was ...
Nationwide study of Escherichia coli producing extended-spectrum ß-lactamases TEM, SHV and CTX-M in Turkey
(2013-11)
Four hundred and forty extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates were collected from 10 different hospitals in Turkey between 2011 and 2012. Clinical specimens consisted of urine (80.45%), ...
Next-generation sequencing of plasmid carrying blaOXA-48 in Klebsiella pneumoniae from Turkey
(2019-02)
A carbapenem-resistant Klebsiella pneumoniae strain was isolated in Turkey in 2012 and blaNDM-1 and blaOXA-48 genes were observed in this strain. The aim of this study was to investigate transferability of plasmid bearing ...
