Lungs from 20 mouflons from the Owl Mountains were examined parasitologically, gross pathologically and histopathologically. In lungs nematodes from the family of Protostrongylidae were found. The number and species of the parasites was determined. Gross pathological examinations revealed the hatching and parasitic noduels. Histological examinations showed various crossections of parasites, heavy inflammatory infiltration, numerous necrotic foci and dystrophic calcification of pathologically changed parts of lungs.
