Nematofauna of bank vole: Clethrionomys glareolus (Schreber, 1780) from Mt. Fruška gora (Serbia)

The nematofauna of bank vole (Clethrionomys glareolus) was analyzed for the first time from samples collected in our country. The specimens were collected in Fruška Gora National Park (locality of Brankovac). The number of collected specimens was 138, and infestation with seven nematode species was determined: Heligmosomum mixtum (Schulz, 1954), Heligmosomoides glareoli (Baylis, 1928), Syphacia petrusewiczi (Bernard, 1966), S. stroma (Linstow, 1884), Capillaria murissylvatici (Dieseng, 1851), Trichocephalus muris Schrank, 1788, and Aspiculuris tetraptera (Nitzsch, 1821). The species Heligmosomum mixtum, Heligmosomoides glareoli, and Syphacia petrusewiczi represent the first records for the territory of our country. The species best represented in the sample were H. glareoli and S. petrusewiczi. There were no statistically significant differences between the sexes of host species regarding the prevalence, mean intensity, or mean abundance of parasite invasion
