Invasive Species Compendium

Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract Full Text

The diversity of parasitic invasions upon the cattle of different ages in the Republic of Moldova.


The level of geoparasite invasion (S. papillosus, N. vitulorum, Eimeria spp.) in cattle decreases with age, probably as a result of immunity, but adult cattle are still carriers for parasitic forms. The level of infestation with other helminths (E. granulosus larvae, F. hepatica, D. lanceolatum) increases with age probably due to long contact with infesting forms on the pasture. The most prevalent [?] species is D. lanceolatum which is characteristic for the steppe and forest steppe ecosystems, where the intermediate hosts and complementary hosts shelter. Absent or irregular deworming, permanent contact of cattle with intermediate and complementary hosts on the pasture, as well as massive pollution of pastures with parasitic elements of different invasive forms, keep a permanently high level of infestation in cattle.
