20.500.12556/RUL-113042 Potential applications of rapid microbiological methods for detection of antibiotic residues in wastewater, surface and well water The goal of the present study was to determine whether the commercial microbiological and tracer assays for the detection of antibiotics in the food were also useful and sensitive enough for testing water samples. Diffusion tests Delvotest® SP-NT and BRT-AiM showed the similar sensitivity to tested antibiotics in spiked water samples. Both tests showed the similar sensitivity to examined antibiotics in water as it was published in milk, while tracer assay BetaStar showed slightly higher minimum detection levels for penicillin and ampicillin but not for cloxacillin. The previous concentration of the samples by lyophilization took place to detect concentrations of antibiotics 100-fold lower than there were the minimum detection limits of the assays. The presence of inhibitory substances in surface and well samples was detected in 16 (16.3 %) cases out of 98 with both ampoule diffusion methods. The positive results were obtained at 15.0 % of surface water samples, while in well water the residues were found also in 16.9 % and 13.6 % samples, using Delvotest SPNT and BRT-AiM, respectively. The β-lactams were detected with BetaStar in 7.5 % of surface water samples. The 12 wastewater samples from hospitals were contaminated with inhibitory substances in 45.5 % (Delvotest SP-NT) or in 36.4 % (BRT-AiM). antibiotics microbiological methods water screening contamination antibiotiki mikrobiološke metode voda presejanje onesnaženje true false false Angleški jezik Slovenski jezik Neznano 2019-11-29 15:33:52 2019-11-29 15:33:52 2022-08-25 03:52:25 0000-00-00 00:00:00 2013 0 0 Str. 31-47 no. 1 Vol. 7 dec. 2013 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 614.777:579.68 1854-0678 URN:NBN:SI:DOC-QEXQHCJE 4640875 216969216 RAZ_Godic_Torkar_Karmen_2013.pdf RAZ_Godic_Torkar_Karmen_2013.pdf 1 43E6BEB977E69B60C61C530C316CBD49 d6a32fcae94aa78d70ce3cb84f43f3e9582c6a9379d972442ec18782a902997d 030f52e0-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125005 http://www.dlib.si/details/URN:NBN:SI:DOC-QEXQHCJE 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125138 Zdravstvena fakulteta 0 0 0
