First record of metacercariae trematodes Opisthioglyphe ranae (Digenea: Telorchiidae) and Echinostoma bolschewense (Digenea: Echinostomatidae) in Dreissena polymorpha (Bivalvia: Dreissenidae) from the Don and Volga river basins, Russia

It is well known that an invasive bivalve mollusk species Dreissena polymorpha plays a significant role as host to parasites. Currently, the interaction between digenean trematodes and their hosts remains relatively poorly understood. In this study we investigate infection of D. by using molecular genetics, histological, light microscopy methods. We obtained sequences one mitochondrial (molecular cytochrome c oxidase subunit 1 (COI)) two nuclear (ITS2, rDNA 28S) gene markers. To best our knowledge, first time metacercariae Opisthioglyphe ranae Echinostoma bolschewense in has been detected. Our sequence was 100% identical 28S O. recorded Penza Oblast (Russia) pond frog. At same time, some detected Ivano-Frankovsk Region (Ukraine) were different from 0.2%. E. sequenced Slovakia. addition, received COI for both trematode ITS2 time.
