Abstract:
The study of the parasitic fauna at the hare (Lepus europaeus Pallas, 1778) from the "Codrii" natural reservation, Republic of Moldova revealed species of parasites that fall taxonomically in 3 classes (Trematoda, Secernentea and Conoidasida), 9 families (Fasciolidae, Dicrocoeliidae, Trichuridae, Strongyloidida, Trichostrongylidae, Oxyuridae,
Trichuridae, Molineidae, Eimeriidae) and 9 genera (Fasciola, Dicrocoelium, Trichuris, Strongyloides, Trichostrongylus, Passalurimus, N and Passalurimus), and Parasitological research has shown an increased level of infestation at hares with various parasitic agents: Tematoda class 2 species (Fasciola hepatica with EI of 7.5% cases and II of 4,6 ex., Dicrocoelium lanceolatum with EI – 11.3% of cases, II-2.4 ex.); Class Secernentea 8 species (Trichocephalus leporis with EI – 16.1% cases, II -7.1 ex., Strongyloides papillosusi with EI – 69.2% cases, II- 14.7 ex., Trichostrongylus retortaeformis with EI – 5.3% cases, II -2.4 ex., Passalurus ambiguus with EI – 34.6% cases, II-5.2 ex., Trcihostrongylus probolurus with EI – 17.1% cases, II- 4,3ex., Trichuris leporis with EI – 7.1% cases, II-3,5ex., Graphidium strigosum with EI – 2.3% cases, II -1,4 ex., Nematodirus abnormalis with EI – 3.7% cases, II- 5.5 ex.) and Conoidasida Class with 6 species: Eimeria leporis with EI – 51.4% cases and II- 18.5 oocysts. Eimeria magna with EI – 31.3% of cases, II- 12.4 oocysts, Eimeria stiedae with EI – 57.1% cases, II- 18.7 oocysts, Eimeria perforans with EI – 12.9% of cases, II- 17.6 oochişti; Eimeria exigua with EI – 48.1% of cases, II- 15.3 oocysts; Eimeria intestinalis with EI – 14.3% of cases, II – 17.2 oocysts. It has been established that hares from the “Codrii” Natural Reserve are infested in the form of monoinvasions in 28,1% of cases, and in the form of polyinvasions - in 71,9% of cases.
