The prevalence of Plaghiorchis elegans was recorded as follows: in Clethrionomys glareolus – 3,8%, Apodemus sylvaticus – 19,2%, in A. agrarius – 11,8% and in the A. flavicollis – 12,8%. The absence of the causal trematode P. elegans in the host species (Microtus rossiaemeridionalis M. arvalis, Cricetulus migratorius, Apodemus uralensis, Mus musculus, M. spicilegus) from dry biotopes is due to the absence of ecological conditions (swamps, ponds, streams) specific for the development of aquatic gastropods, fish (intermediate hosts) and aquatic insects or crustaceans (complementary hosts), involved in the biological cycle of the parasite.

Prevalenta cu Plaghiorchis elegans a fost înregistrata dupa cum urmeaza: la Clethrionomys glareolus – 3,8%, la Apodemus sylvaticus – 19,2%, la A. agrarius – 11,8% si la A. flavicolis – 12,8%. Lipsa trematodului cauzal P. elegans la speciile gazde (Microtus rossiaemeridionalis M. arvalis, Cricetulus migratorius, Apodemus uralensis, Mus musculus, M. spicilegus) din biotopuri uscate, se datoreaza absentei conditiilor ecologice (mlastini, balti, pâraie, râuri, lacuri) specifice pentru dezvoltarea gasteropodele acvatice, pestilor (gazdelor intermediare) insectelor acvatice si crustaceelor (gazde complementare), implicate în ciclul biologic al parazitului.
