Development, in-house validation and application of a method using high-performance liquid chromatography with fluorescence detection (HPLC-FLD) for the quantification of 12 ergot alkaloids in compound feeds
Kowalczyk, Ewelina; Kwiatek, Krzysztof (National Veterinary Research Institute in Pulawy; Poland, 2023)Introduction: Ergot alkaloids (EAs) are toxic substances naturally produced by Claviceps fungi. These fungi infest a widerange of cereals and grasses. When domestic animals are exposed to EAs through contaminated feeds, ... -
Lysins as a powerful alternative to combat Bacillus anthracis
Nakonieczna, Aleksandra; Abramowicz, Karolina; Kwiatek, Magdalena; Kowalczyk, Ewelina (Springer, 2024)This review gathers all, to the best of our current knowledge, known lysins, mainly bacteriophage-derived, that have demonstrated activity against Bacillus anthracis strains. B. anthracis is a spore-forming, toxin-producing ... -
Risk assessment of rare earth elements, antimony, barium, boron, lithium, tellurium, thallium and vanadium in teas
Kowalczyk, Ewelina; Givelet, Lucas; Amlund, Heidi; Sloth, Jens Jørgen; Hansen, Max (2022)In recent years, a great intensification in the use of various elements especially in modern technologycan be observed. However, the anthropogenic activities, including industrialisation, urbanisation orintensive agriculture, ... -
Scopolamine and atropine in feeds – determination with liquid chromatography mass spectrometry
Kowalczyk, Ewelina; Kwiatek, Krzysztof (2022)Tropane alkaloids (TAs) are naturally occurring plant toxins. Due to the fact that TA-producing plants can enter the food chain, they pose a risk for animals and human health. Therefore, sensitive analytical methods need ... -
Simultaneous determination of pyrrolizidine and tropane alkaloids in honey by liquid chromatography–mass spectrometry
Kowalczyk, Ewelina; Kwiatek, Krzysztof (National Veterinary Research Institute in Pulawy; Poland, 2022)Introduction: Pyrrolizidine alkaloids (PAs) and tropane alkaloids (TAs) are natural contaminants of honey and respectively hepatoxic and neurotoxic compounds. Because honey is a popular constituent of the human diet, it ...
