A 21-day-long experiment was performed on 160 one-day-old “Ross" broiler chicks. This research was done with the aim of investigating pathomorphological changes in broilers exposed to a relativly small amount of T-2 toxin (2 ppm) and the possibility of prevention and/or alleviating adverse effects of T-2 toxin using various feed additives. Pathohistological examination showed negative consequen...
The effect of T-2 toxin on the nerve cell membrane was investigated using 25 unidentified neurons of the visceral ganglion of the mollusc Lymnaea stagnalis .The method was performed by intracellular dialysis and perfusion of neurons under fixation of tension on these membranes.T-2 toxin within concentrations occurred between 10 -6 to 10 -3 mol / L blocked delayed potassium ion current I s k amp...
Abstract Trichothecenes are among the most important fusariotoxins. According to their chemical structure, they divided into 4 groups (A – D). In terms of agriculture, trichothecenes A and B greatest importance. this study, incidence (deoxynivalenol T-2 toxin) in mixed feed for broilers turkeys were determined. Deoxynivalenol was detected all analysed samples mixture (100 %) at an average conce...
The Fusarium mycotoxins HT-2 toxin (HT2) and T-2 toxin (T2) are frequent contaminants in oats. These toxins, but also their plant metabolites, may contribute to toxicological effects. This work describes the use of 13C-assisted liquid chromatography-high-resolution mass spectrometry for the first comprehensive study on the biotransformation of HT2 and T2 in oats. Using this approach, 16 HT2 and...
A survey was made to detect microorganisms useful for assaying butenolide [4-acetamido-4-hydroxy-2-butenoic acid gamma-lactone] and T-2 toxin [4beta, 15-diacetoxy-8alpha-(3-methylbutyryloxy)-12,13-epoxytricothec -9-en-3alpha-ol]. These mycotoxins produced by strains of Fusarium tricinctum have been implicated in mycotoxicosis of livestock. Although butenolide proved to be a very weak antibiotic...
To evaluate the effectiveness of a superactivated charcoal (SAC) in alleviating mycotoxicosis, two experiments were conducted in which 432 male broiler chicks (216 per experiment) were fed diets containing 4 mg aflatoxin (AF) or 6 mg T-2 toxin/kg of diet, with and without 0.5% SAC, from 1 to 21 d of age. Feeding AF and T-2 toxin significantly decreased BW gain over the 21-d experimental period....
The mycotoxin T-2 toxin and Salmonella Typhimurium infections pose a significant threat to human and animal health. Interactions between both agents may result in a different outcome of the infection. Therefore, the aim of the presented study was to investigate the effects of low and relevant concentrations of T-2 toxin on the course of a Salmonella Typhimurium infection in pigs. We showed that...
To investigate the metabolic fate of HT-2 toxin (HT2) and T-2 toxin (T2) in wheat (Triticum aestivum L.), an untargeted metabolomics study utilizing stable isotopic labeling and liquid chromatography-high resolution mass spectrometry was performed. In total, 11 HT2 and 12 T2 derived in planta biotransformation products were annotated putatively. In addition to previously reported mono- and digl...
Mycotoxins (frequently referred to as secondary metabolites of toxigenic fungi) are commonly found in foodstuffs and essential because their association with disease. The current study investigated the teratogenic potential characteristics T-2 trichothecenes mycotoxins produced by Fusarium Trichoderma, which reportedly toxic humans animals pregnant mice. toxin is a cytotoxic fungal metabolite t...
