Coexistence of Lateriporus teres (Cestoda: Dilepididae) and Polymorphus phippsi (Palaeacanthocephala: Polymorphidae) in the intestine of common eider
The purpose of the research is studying the peculiarities of parasite infection of the cestodes Lateriporus teres Krabbe, 1869 (Cestoda: Dilepididae) and acanthocephalans Polymorphus phippsi Kostylew, 1922 (Palaeacanthocephala: Polymorphidae) during coexistence in the intestine of the common eider,...
