[The transformation of the saprotrophic mycelial form of the fungus Paecilomyces variotii into the tissue parasitic form and its morphological characteristics].
The fungus Paecilomyces variotii is known to develop as a saprotrophic mycelial form in the soil. When penetrating into the human organism or placing into a medium containing cultured cells it transforms into a parasitic flesh form. This form of the fungus was shown to undergo 3 morphological stages: endospore, juvenile (intermediate) form and mature sphaerula. The transformation of the mycelial form into parasitic one occurs in the biological media containing cells of the host, inside or outside the cell. The morphological structure of mycelium of P. variotii developed from the flesh parasitic form is different in aerobic and anaerobic conditions. In the former case, the spore production takes place by means of phialides, and in the latter case it occurs inside the mycelium.
