Аннотация

Data on the trematoda Nematostrigea serpens in the Republic of Karelia are presented. This parasite was found in the intestine of an osprey (Pandion haliaetus L. 1758) for the first time. A brief morphological characterization, description, and drawings of the parasite and its differential diagnosis with closely related species are given. A nucleotide sequence of LSU D1–D3 (28S) rRNA was obtained and deposited in the GenBank (KF434762).
