Nationwide study of Escherichia coli producing extended-spectrum beta-lactamases TEM, SHV and CTX-M in Turkey
(Nature Publishing Group, 2013)
Four hundred and forty extended-spectrum beta-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%), ...
OXA- and GES-type beta-lactamases predominate in extensively drug-resistant Acinetobacter baumannii isolates from a Turkish University Hospital
(Elsevier Sci Ltd, 2014)
We determined the antibiotic susceptibility and genetic mechanisms of resistance in clinical strains of Acinetobacter baumannii from Istanbul, Turkey. A total of 101 clinical strains were collected between November 2011 ...
Determination of a novel integron-located variant (bla(OXA-320)) of class D beta-lactamase in Proteus mirabilis
(Wiley, 2014)
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 ...
Distribution of beta-lactamase genes among carbapenem-resistant klebsiella pneumoniae strains isolated from patients in Turkey
(Korean Soc Laboratory Medicine, 2015)
Background: the emergence of carbapenem-resistant Klebsiella pneumoniae poses a serious problem to antibiotic management. We investigated the beta-lactamases in a group of carbapenem-resistant K. pneumoniae clinical isolates ...
Kinetic characterization of GES-22 beta-lactamase harboring the M169L clinical mutation
(Japan Antibiotics Research Assoc, 2016)
The class A p-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 ...
Comparison of verona integron-borne metallo-beta-lactamase (VIM) variants reveals differences in stability and inhibition profiles
(Amer Soc Microbiology, 2016)
Metallo-beta-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-beta-lactamase ...
Detection of class 1 integron in Acinetobacter baumannii isolates collected from nine hospitals in Turkey
(Elsevier, 2013)
Objective: To investigate the antibiotic resistance genes inserted into class 1 and class 2 integrons in Acinetobacter baumannii (A. baumannii) isolates obtained from nine different cities in Turkey. Methods: A collection ...
