[Morphological polymorphism of the cestode Proteocephalus longicollis Zeder, 1800 (Cestoda: Proteocephalidae) through the ontogeny].
The qualitative diversity of Proteocephalus longicollis through the ontogeny was studied: procercoids from copepods, immature and mature cestodes from the vendace Coregonus albula L. The structure of the P. longicollis population was found to be made up of the dominant phenotypes: by the scolex shape--Sc2, by the sucker arrangement type--SI, by the proglottid shape--P3, by the ovary lobe shape--01, by the testes arrangement type -T2. Some rare and scant phenotypes are also present. It is shown that the structure of the parasite phenotypes is relatively stable through the ontogeny. The assumption is made about the high survival rate of the S2 sucker phenotype.
