[A method for determining the toxigenicity of micromycetes].

A method is suggested to determine toxigenicity of microscopic fungi from genera Aspergillus, Penicillium, Fusarium, etc. which contaminate fodder, food products and environment objects. The method is based on the property of micromycetes isolated from fodder, food products and environment objects to produce mycotoxins under optimal conditions of their cultivation on the nutrient media. Their further extraction by the organic solvent, evaporation and emulsification of the extract and its peroral introduction to young female rats cause a disease and death of animals. The suggested method may be used for recognizing and preventing mycotoxicoses of farm animals and poultry.
