Parasitological studies of the species from genus Apodemus (Rodentia, Muridae) from the "Plaiul Fagului" natural reserve, Republic of Moldova.
The research was carried out in the "Plaiul Fagului" Reserve in THE spring-summer period of 2015. During the study period, 202 individuals from 6 small rodent species were registered. The diversity was higher in spring, when all 6 species have been recorded, and lower in autumn with 4 species. In all the studied biotopes the Apodemus genus species (A. flavicollis, A. sylvaticus, A agrarius) were dominant. For parasitological studies, only the species of the genus Apodemus were considered, because they had the highest abundance and represented more than 80% of all small rodent community. The taxonomic structure of helminth fauna in the investigated specimens falls into 3 classes, 6 families, 7 genera and 8 species. The diversity of parasitic invasions is represented by 4 species of the class Cestoda, 3 species of class Secernentea and 1 species of the class Adenophorea. In A. flavicolis the most diverse parasite structure was determined, which is represented by 4 parasite species from class Cestoda, 3 species from class Secernentea and 1 species from the Adenophorea class. From the total of 7 parasite species, 2 have a zoonotic impact (Syphacia stroma, Syphacia obvelata). The helminth fauna in studied rodent species consists of 8 parasite species, of which 3 species of biohelminths (37.5%), 2 species of geohelminths (25.0%) and 2 species of ageohelminths (25.0%). The most abundant parasite species proved to be Syphacia stroma and Syphacia obvelata.
