Structura parazitismului la șoarecele scurmător in ecosisteme forestiere

Bank vole (Myodes glareolus) is widely spread silvicolous species, inhabiting in woods, forest clearings, shrub vegetation, at forest edge, near ponds with abundant vegebtation. The parasite fauna is structured of 3 classes, 13 families, 14 genera and 15 species, of which 6.6% belong to class Trematoda, 46.7% to class Cestoda and 46.7% to class Nematoda. The results of the parasitological investigations show a prevalence of Plaghiorchis elegans of 13.8% and an average intensity of 3.8 ex, respectively with Mesocestoides lineatus larvae 14.0%, 1.5 ex, Paranoplocephala omphaloides - 10.3%, 2.7 ex, Rodentolipis straminea - 69.0%, 3.0 ex, Hydatigera taeniaeformis larvae - 10.3%, 1.0 ex, Catenotaenia cricetorum - 10.3%, 2.7 ex, Skrewabinotaenia lobata - 3 ex, Taenia pisiformis - 13.7%, 1.0 ex, Capillaria hepatica - 27.5% and liver infestation is about 50.0% (++), Syphacia stroma - 17.2%, 94 ex, Syphacia obvelata - 24,1%, 84,9 ex, Heligmosomoides polygirus - 10,0%, 5,3 ex, Strongyloides ratti - 6,9%, 23,3 ex, Mastophorus muris - 17,2%, 3 , 6 ex and Trichocephalus muris 17.2%, intensity 3.8 ex. The share of the Trematoda species is 6.6%, in the Cestoda class - 46.7%, and in the Nematoda class - 46.7%. The massive abundance of foxes on large land surfaces, including ecological plasticity with tendency toward synantropization, are the primary factors in the formation, maintenance and spreading of parasitosis outbreaks in natural and anthropic ecosystems. The aim of the research is to study the diversity of parasite fauna in Myodes glareolus from forest ecosystems with specifying the parasite taxonomic structure and determining the degree of infestation.
