Experimental Infections of Muskoxen ( Ovibos moschatus ) and Domestic Sheep with Umingmakstrongylus pallikuukensis (Nematoda: Protostrongylidae): Parasite Development, Population Structure, and Pathology
Three captive muskoxen (Ovibos moschatus) were successfully infected with third-stage larvae of Umingmakstrongylus pallikuukensis digested or emerged from the slugs Deroceras reticulatum and D. laeve, for the first time completing the life cycle of this parasite under experimental conditions.
