[The outer membranes of the eggs of Opisthorchis felineus and Clonorchis sinensis].

The outer coats of Opisthorchis felineus and Clonorchis sinensis eggs have been examined by scanning electron microscopy. The outer coat turned to be extremely sculptured, presenting as interlaced crests of various height. The authors suggested the possibility of using this indicator in the taxonomy of Opisthorchiidae and studying their distribution in biocenoses as well as their ability of accumulating on the leaves of aquatic plants, thus facilitating the contact with their intermediate hosts the mollusks.
