Submicroscopic Changes in the Hepatopancreas of Freshwater Mollusks Infected with Parthenites of Trematodes Echinoparyphium aconiatum (Echinostomida) and Plagiorchis elegans (Plagiorchiida)

The study contains the results of the electron microscopic research of the hepatopancreas of Lymnaea stagnalis (Linné, 1758) molluscs infected by the Plagiorchis elegans (Rudolfi, 1802) Braun, 1902 and Echinoparyphium aconiatum Dietz, 1909 trematodes. With a high degree of invasion, fibrous connecti...
