Hospital wastewaters (HWWs) are reported to be hotspots for antibiotics and antibiotic-resistant bacteria. However, limited information involves the impact of these effluents on dissemination of antibiotic-resistance genes (ARGs). In this study, therefore, seasonally collected HWWs were monitored for overall bacterial load and seven ARGs aadA, tetA, cmlA, sul1, qnrS, ermB and bla CTX-M by using quantitative polymerase chain reaction method. Overall bacterial 16S rRNA copy number was found to be the lowest in winter with 103 copy number/mL, while the highest copy number, with 105 copy number/mL, was observed in both summer and spring. All hospitals tested displayed similar seasonal ARG copy number profile of aadA > tetA > cmlA ≈ sul1 > ermB ≈ qnrS > bla CTX-M. The results indicated that untreated HWWs were hotspots for ARGs and required attention before discharging into public sewer.

VanA-Type MRSA (VRSA) Emerged in Surface Waters İçgen, Bülent (Springer Science and Business Media LLC, 2016-09-01) Due to the widespread occurrence of mecA-encoded methicillin resistance in Staphylococcus aureus (MRSA), treatment of staphylococcal infections is shifted to glycopeptide antibiotics like vancomycin and teicoplanin. The selective pressure of glycopeptides has eventually led to the emergence of staphylococci with increased resistance. Of great concern is vanA-encoded high level vancomycin and teicoplanin resistance in MRSA (VRSA). Therefore, this study aimed at investigating the occurrence of VRSA in surface...
Impact of untreated hospital effluents on dissemination of antibiotic resistance genes Kayalı, Osman; İçgen, Bülent; Department of Biotechnology (2019) Hospital wastewaters (HWWs) were reported to be hotspots for antibiotics and antibiotic-resistant bacteria. However, little is known about the impact of these effluents on the dissemination of antibiotic-resistance genes (ARGs). In this study, therefore, HWWs were monitored for 16S rRNA gene for overall bacterial genes and seven ARGs of aadA, tetA, cmlA, sul1, qnrS, ermB and blaCTX-M corresponding to commonly used antibiotics aminoglycosides, tetracyclines, amphenicols, sulfonamides, quinolones, macrolide-l...
Diameter of titanium nanotubes influences anti-bacterial efficacy Ercan, Batur; Alpaslan, Ece; Webster, Thomas J. (IOP Publishing, 2011-07-22) Bacterial infection of in-dwelling medical devices is a growing problem that cannot be treated by traditional antibiotics due to the increasing prevalence of antimicrobial resistance and biofilm formation. Here, due to changes in surface parameters, it is proposed that bacterial adhesion can be prevented through nanosurface modifications of the medical device alone. Toward this goal, titanium was created to possess nanotubular surface topographies of highly controlled diameters of 20, 40, 60, or 80 nm, some...
FTIR spectroscopy offers hints towards widespread molecular changes in cobalt-acclimated freshwater bacteria Kardaş, Mehmet; Gözen, Ayşe Gül; Severcan, Feride (Elsevier BV, 2014-10-01) High concentrations of heavy metals can be toxic for bacteria. However, after prolonged exposure, bacteria can become acclimated and begin to be able to grow in the presence of heavy metals. Acclimation can involve alterations of metabolism and molecular structures. Our aim was to examine these alterations in cobalt-acclimated bacteria via attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy on viable samples. Bacillus sp. and Pseudomonas sp. isolated from a temperate shallow lake ...
Cellular uptake, genotoxicity and cytotoxicity of cobalt ferrite magnetic nanoparticles in human breast cells Asik, Elif; Akpinar, Yeliz; Güray, Nülüfer Tülün; Iscan, Mesude; ÇAKMAK DEMİRCİGİL, GONCA; Volkan, Mürvet (Oxford University Press (OUP), 2016-01-01) Magnetic nanoparticles (MNPs) have been increasingly used for many years as MRI agents and for gene delivery and hyperthermia therapy, although there have been conflicting results on their safety. In this study, cobalt ferrite magnetic nanoparticles (CoFe-MNPs) were prepared by the co-precipitation method and their surfaces were modified with silica by the sol-gel method. The particle and hydrodynamic sizes, morphology and crystal structure of the bare and silica-coated CoFe-MNPs were evaluated by transmiss...
