Helminths in Myomorph Rodents (Rodentia, Myomorpha) from the National Park “Smolny” and Its Surroundings (European Russia)

The National Park “Smolny” is a large forest area, located in the center of European Russia. helminth fauna myomorph rodents was studied for first time within 2018–2020. Rodents were examined by method complete helminthological dissection. A total 30 species parasites recorded 11 rodent species: 6 trematodes, cestodes and 13 nematodes. trematode Plagiorchis maculosus (Rudolphi, 1802) found Clethrionomys glareolus (Schreber, 1780) from Russian time. Microtus arvalis (Pallas, 1779) are new hosts P. metacestode Versteria mustelae (Gmelin, 1790), respectively. most widespread eurybiont have diverse rich fauna, such as C/ (14 species), Apodemus agrarius 1771) (12) Sylvaemus uralensis 1811) (10). less flavicollis (Melchior, 1834), M. (7 each), agrestis (Linnaeus, 1761) (5), subterraneus (de Selys-Longchamps, 1836) (3), Sicista betulina (2) Arvicola amphibius 1758) (1). Comparative analysis small with micromammals other regions Russia revealed that high similarity areas reaches subterraneus, S. flavicollis, uralensis, betulina, A. agrestis.
