Parasitic fauna at the hare (Lepus Europaeus Pallas, 1778) from the "Codrii" natural reservation, Republic of Moldova

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.
