title: [The microstructure of trematodes studied by electron microscopy].
abstract: The main tendencies in the studies into the ultrastructure of trematodes (including species of medical importance) using scanning and transmission electron microscopy are considered. Attention was paid to disproportions in the studies into the different developmental stages of trematodes: maritae are better studied than parthenogenetic and larval stages and especially eggs and miracidia. During the last years the number of studies using the complex of histochemical, radioisotope and electron microscopic methods is increasing, among them the investigations on the changes caused by modern anthelmintic agents in the tegument and viscera of trematodes. These are mainly the trematodes of Schistosomatidae, Echinostomatidae, Fasciolidae and Paragonimidae families that were studied by electron microscopy, and the studies on Opisthorchidae are very scarce.
