Antimicrobial resistance of pathogenic microorganisms is an emerging public health concern. Intensive use of antibiotics in food animals might increase antimicrobial resistance in foodborne pathogens. Colistin is a last resort antibiotic for treatment of multidrug resistant (MDR) Gram negative pathogens. The recent antimicrobial resistance studies revealed a mobile antimicrobial resistance gene (mcr) that provides resistance to colistin. Furthermore, the gene has been found in different genera. Therefore, the aim of this study was to determine colistin resistance of Escherichia coli isolates (N=48) isolated in between 2011 and 2015 from food samples in Turkey. In addition, 5 mcr genes and their variants were screened by performing PCR on resistant isolates. 4 E. coli isolates were found resistant to colistin above the epidemiological cut-off value (Minimum inhibitory concentration (MIC) > 2mg/L). None of the resistant isolates had the mcr genes. Further studies with human and food isolates should be conducted to figure out which gene or genes are responsible for colistin resistance.

Investigation of plasmid mediated colistin resistance phenotypically and genotypically in Salmonella and E. coli isolates in Turkey
Tok, Seray; Soyer, Yeşim; Department of Food Engineering (2022-5-31)
Today, colistin is used as the last resort antimicrobial against Gram-negative bacteria. Excessive use of colistin caused resistance among bacteria. Recent studies showed presence of plasmid mediated mcr genes, encoding colistin resistance that can be transferred horizontally between different bacterial species. In this study, it was aimed to investigate colistin resistance and change in colistin resistance rate in E. coli and Salmonella isolates over time from different cities in Turkey. For this aim, we...

Many antimicrobial drugs are going to become resistant to different pathogens, so the discovery of new antimicrobial products is an important public health concern. Nardostachys jatamansi (D. Don) DC (Valerianaceae) is an important traditional herbal medicine used as tranquillizer. CNS sedative. antiepilepsy, cardiotonic. diuretic, heptatonic, analgesic and in boils, itch and eye diseases. Carbonic anhydrase inhibitors are the potential source of treatment in case of glaucoma, hypertension and epilepsy and ...
AN ALTERNATIVE WAY FOR REDUCTION OF SALMONELLA IN POULTRY PRODUCTS: BACTERIOPHAGES
Güzel, Mustafa; Soyer, Yeşim; Akçelik, Mustafa; Department of Biotechnology (2022-6-03)
Antibiotic resistance of pathogenic microorganisms is a severe public health problem. One of the main reasons of the resistance is the overuse of antibiotics in veterinary and food animals. Non-typhoidal Salmonella is a major foodborne pathogen that causes millions of cases each year, worldwide. Although Salmonella causes outbreaks in almost all food commodities, it is mostly associated with poultry. In addition to high prevalence in poultry, Salmonella isolates recovered from poultry have shown multi drug ...
Co-occurrence of Antibiotic and Heavy Metal Resistance in Kizilirmak River Isolates
İçgen, Bülent (2014-12-01)
Contamination of surface waters with antimicrobials has become an increasing public health concern because of the emergence of multi-resistant pathogens. For this reason, water samples collected from the Kizilirmak River-Kirikkale, Turkey were analysed to learn more about the co-occurrence of heavy metal and antibiotic resistance in bacteria. Resistant profiles were determined by using 26 antibiotics and 17 heavy metals. Out of 290, 24 isolates with both heavy metal and antibiotic resistance were determined...
Study on Cost-Efficient Carbon Aerogel to Remove Antibiotics from Water Resources
Aylaz, Gülgün; Okan, Meltem; Duman, Memed; Aydin, Halil Murat (American Chemical Society (ACS), 2020-6-28)
Because of pharmaceutical-emerging contaminants in water resources, there has been a significant increase in the antibiotic resistance in bacteria. Therefore, the removal of antibiotics from water resources is essential. Various antibiotics have been greatly studied using many different carbon-based materials including graphene-based hydrogels and aerogels. In this study, carbon aerogels (CAs) were synthesized from waste paper sources and their adsorption behaviors toward three antibiotics (hygromycin B, ge...
