Antibiotic resistance profile of Enterococcus faecium and Enterococcus faecalis isolated from broiler cloacal samples
Unal, Nilgun; Askar, Sinasi; Yildirim, Murat (Scientific Technical Research Council Turkey-Tubitak, 2017)The present study was performed to isolate and identify Enterococcus spp. from broiler cloacal samples to species level, to determine their resistance patterns to various antibiotics, and to detect vancomycin resistance ... -
Detection of stapylococcal enterotoxin, methicillin-resistant and Panton-Valentine leukocidin genes in coagulase-negative staphylococci isolated from cows and ewes with subclinical mastitis
Unal, Nilgun; Cinar, Oya Dogu (Springer, 2012)Coagulase-negative staphylococci (CNS) are the most prevalent mastitis pathogens. However, virulence characteristics of CNS have not been well determined. The presence of genes for enterotoxins (sea-sej), toxic shock ... -
Detection of vancomycin-resistant enterococci in samples from broiler flocks and houses in Turkey
Unal, Nilgun; Bal, Erhan; Karagoz, Alper; Altun, Belgin; Kocak, Nadir (AKADEMIAI KIADO ZRT, 2020)Vancomycin-resistant enterococcus (VRE) is a global threat to public health. Knowledge about the occurrence of vanA-carrying enterococci in broiler and environmental samples is important as antibiotic resistance can be ... -
Development and characterization of polymeric-based nanoparticles for sustained release of amoxicillin - an antimicrobial drug
Guncum, Enes; Isiklan, Nuran; Anlas, Ceren; Unal, Nilgun; Bulut, Elif; Bakirel, Tulay (Taylor & Francis Ltd, 2018)In this study, amoxicillin (AMO)-loaded poly(vinyl alcohol)/sodium alginate (PVA/NaAlg) nanoparticles were prepared as a polymer-based controlled release system. The physicochemical properties of the obtained nanoparticles ... -
Extended-spectrum beta-lactamases among cloacal Escherichia coli isolates in healthy broilers in Turkey
Unal, Nilgun; Karagoz, Alper; Askar, Sinasi; Dilik, Zahide; Yurteri, Buket (Scientific Technical Research Council Turkey-Tubitak, 2017)The aim of this study was to determine the prevalence and clonal typing of extended-spectrum beta-lactamase (ESBL)producing Escherichia coli in healthy broilers in Turkey. Three hundred broiler cloacal samples were collected ... -
Investigation of antimicrobial resistance and extended spectrum beta- lactamase production in Escherichia coli isolates of equine feces origin
Ornek, Gamze; Unal, Nilgun (Ankara Univ Press, 2016)In this study, it was aimed to investigate the existence of ESBL and determine the resistance against various antibiotics of E. coli strains isolated from feces examples obtained from racing and jumping horses. One hundred ... -
Investigation of some toxins genes and methicillin resistance gene in Staphylococcus aureus isolates from cows with subclinical mastitis
Unal, Nilgun (Ankara Univ Press, 2013)The aim of this study was to investigate the genes of some staphylococcal enterotoxins and Panton-Valentine leukocidin and methicillin resistance of Staphylococcus aureus strains isolated from subclinical bovine mastitis. ... -
Isolation of a vanA Positive Enterococcus faecium from Commercial Broiler Farms in Turkey
Unal, Nilgun; Dilik, Zahide; Yildirim, Murat (Kafkas Univ, Veteriner Fakultesi Dergisi, 2010)In this study, the vanA gene indicating Vancomisin Resistance Enterococcus (VRE) was ascertained from swab samples (n=400) collected from commercial broiler farms. VRE was isolated only from a single sample and identified ... -
Panton-Valentine leukocidin and some exotoxins of Staphylococcus aureus and antimicrobial susceptibility profiles of staphylococci isolated from milks of small ruminants
Unal, Nilgun; Askar, Sinasi; Macun, Hasan Ceyhun; Sakarya, Fatma; Altun, Belgin; Yildirim, Murat (Springer, 2012)The aims of this study were to determine the existence of pvl gene, some toxin genes, and mecA gene in Staphylococcus aureus strains isolated from sheep milk and to examine antimicrobial resistance profiles in staphylococci ... -
Phenotypic and genotypic features of Staphylococcus aureus strains isolated from cattle and humans
Unal, Nilgun; Istanbulluoglu, Ersin (Ankara Univ Press, 2009)The aim of this study was to determine susceptibility patterns of S. aureus strains (46 were isolated from bovine milk samples with mastitis, 35 from bovine teat skins, 3 from bovine noses, 3 from caretaker hands and 3 ... -
The Relationship of Coxiella burnetii Seropositivity Between Farm Animals and Their Owners: A Pilot Study
Dogru, Aylin Kasimoglu; Yildirim, Murat; Unal, Nilgun; Gazyagci, Serkal (Medwell Online, 2010)Q fever is a zoonotic disease caused by Coxiella burnetii. This study aimed to detect the relationship of C. burnetii seropositivity between farm animal owners and their animals. Blood serums of 20 farm animal owners, 32 ...
