Effect of saprotrophic soil fungi Penicillium frequentans and Stachybotrys chartarum on respiratory metabolism of Ascaris suum, during its embryogenesis was determined using histoenzymatic methods. Based on histochemical assessment of the enzyme actvity (glycolysis-lactate dehydrogenase-LDH; tricarboxylic acid cycle-succinate dehydrogenase-SDH) changes in the energy metabolism of developing eggs of A. suvm were detected. Of the fungi species tested - P. frequentans caused the most extensive disorders in the processes of cellular oxidation, which were manifested in a decline of SDH activity during gastrulation. Incubation of eggs of Ascaris with mycelia of both fungi: S. chartarum and P. frequentans - in lesser extend affected respiratory metabolism in embryogenesis of this nematode
