Andriychuk A. Micobiots of barley grain, biosynthesis and biological action of ochratoxin A

The object of study – micobiots of barley grain, biosynthesis of mycotoxicness, ochratoxicosis of quails and mouses. Methods of study –micologyc, micotoxic, chemical- toxicological, chromatographic, clinical, biochemical, path- anatomical, histological and mathematic-statistical. The science novelty: There were established the quantitative content epifitna and endofitna of microbial of barley grain, was studied toxicness of some fungus Aspergillus and Fusarium. A reliable difference is exsposed in contaminated grains by the fungus Aspergillus and Penicillium, which are got in forest- steppe, marshy- woodlands, steppes. There was developed the express- method of determination of the ability to produce F-2 toxin by Fusarium species there was obtained the declarative patent № u 200508728 (the method of express determination of ability of fungus of Fusarium species to produce F-2 toxin. Proposed: methodic of express-method of determination of ability of fungus of Fusarium species to produce F-2 toxin. Introduced: The method of express determination of ability of fungus of Fusarium spp. to produce F-2 toxin offered for application in public diagnostic institutions of veterinary medicine, laboratories of researches of scientific establishments of types and in an educational process on the faculties of veterinary medicine of agrarian institutes of higher. Using area : veterinary medicine.
