Antimicrobial resistance patterns and integron carriage of Escherichia coli isolates causing community-acquired infections in Turkey

Çopur Çiçek, Ayşegül; Özgümüş, Osman Birol; Saral, Ayşegül; Sandallı, Cemal (Korean Society for Laboratory Medicine, 2014)

We aimed to observe antimiCrobial resistance patterns and integron carriage of Escherichia coli isolates causing community-acquired infections. Two hundred sixty-eight E. coli strains were obtained from outpatients with ...

Characterization of novel VIM carbapenemase, VIM-38, and first detection of GES-5 carbapenem-hydrolyzing β-lactamases in Pseudomonas aeruginosa in Turkey

Iraz, Meryem; Düzgün, Azer Özad; Çopur Çiçek, Ayşegül; Bonnin, Remy A.; Ceylan, Ayşenur; Saral, Ayşegül; Nordmann, Patrice; Sandallı, Cemal (Elsevier Science INC, 2014)

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), ...

Determination of antibiotic resistance genes and virulence factors in Escherichia coli isolated from Turkish patients with urinary tract infection

Düzgün, Özer Özad; Okumuş, Funda; Saral, Ayşegül; Çopur Çiçek, Ayşegül; Cinemre, Sedanur (Soc Brasileira Medicina Tropical, 2019)

Introduction: Escherichia coli ranks among the most common sources of urinary tract infections (UTI). Methods: Between November 2015 and August 2016, 90 isolates of E. coli were isolated from patients at Rize Education ...

Clinical variants of the native class d beta-lactamase of acinetobacter baumannii pose an emerging threat through ıncreased hydrolytic activity against carbapenems

Schroder, Emma C.; Klamer, Zachary L.; Saral, Ayşegül; Sugg, Kyle A.; June, Cynthia M.; Wymore, Troy; Szarecka, Agnieszka; Leonard, David A. (Amer Soc Microbiology, 2016)

The threat posed by the chromosomally encoded class D beta-lactamase of Acinetobacter baumannii (OXA-51/66) has been unclear, in part because of its relatively low affinity and turnover rate for carbapenems. Several hundred ...

Next-generation sequencing of plasmid carrying blaOXA-48 in Klebsiella pneumoniae from Turkey

Düzgün, Azer Özad; Saral, Ayşegül (Akademia Kiado ZRT, 2019)

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 ...

Kinetic characterization of GES-22 beta-lactamase harboring the M169L clinical mutation

Saral, Ayşegül; Leonard, David A.; Düzgün, Azer Özad; Çopur Çiçek, Aysegül; June, Cynthia M.; Sandallı, Cemal (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 ...

Isolation and characterization of native bacillus thuringiensis from Artvin, Turkey, and screening against hypantaria cunea (lepidoptera)

Albayrak İskender, Nurcan; Saral, Ayşegül (Parlar Scientific Publications, 2017)

The soil in different regions may contain new B. thuringiensis species which may be toxic for the harmful insects. For this purpose, 5 native B. thuringiensis strains (Na1, Na2, Na5, Na7, Na25) were isolated from the soil ...

Isolation, identification and characterization of biotechnologically important bacteria from microflora of Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae)

Albayrak İskender, Nurcan; Algur, Ömer Faruk; Aksu, Yaşar; Saral, Ayşegül (Taylor & Francis Inc, 2017)

The chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) is one of the most important insect pests of chestnut. The aim of this study was to isolate and characterize bacteria from D. kuriphilus to ...
