Abstract: | The analysis of the action of various anthelmintics on the integuments and digestive system of Strongylate nematodes indicated that all the used agents caused varying structural disorders. The swelling of the cuticle and its detachment from the subcuticle occurred with the overwhelming majority of the anthelminths on the integuments of the Strongylate nematodes. The digestive system showed an ample epithelial vacuolation in the intestinal wall, as well as swelling and destruction in the mitochondria and endoplasmic reticulum. Almost all the used agent lowered the levels of glycogen and RNA in the tissue of Strongylate nematodes. |
