[Ostracod, Eucypris infiata, the intermediate host of avian cestodes in the biocenosis of Lake Tengiz].

In the biocoenosis of the Lake Tengiz (Central Kazakhstan) Eucypris inflata (0.3--11%) was found to be spontaneously infected with the larvae of cestodes-hymenolepidids (6 species) and dilepidids (1 species). The nesting flamingos and moulting grebes from the same water body were also infected to a great extent with these cestodes. Figures and morphological description of cysticercoids (7 species) and skolex of mature cestodes of Parabiglandatrium phoenicopteri are given.
