Using the method of thin-layer chromatography there were investigated the chloroform extracts of 30 dermatophyte mycelia. It was found the presence of aflatoxin-like compounds in six mycelium extracts only, which chromatograms showed the equal Rf and the colour of the strains to the strains to the standard aflatoxin extract of bruished peanuts grain Rossetti. Those six mycelia were: Epidermophyton floccosum, Nannizzia fulva, N. persicolor, Arthroderma gloriae, Trichophyton concentricum and T. Gallinae.
