Lungworm disease of five Japanese serows was studied parasitologically and pathologically. All cases were found in the water near Towada of Aomori Prefecture in the term from April to June, 2000. The parasites isolated from the nodules in the lung were identified into Protostrongylus shiozawai. Their fine morphology was observed by scanning electron microscopy. Pathologically, hyperplasia of smooth muscle bundles and lymphatic apparatus in the lung interstitium was characterized concerned with parasitizm. In addition, characteristic aqueous emphysema that developed in the non-parasitized tissue was suggested as the possible cause of their accidental death in the water. This is the first report about P. shiozawai parasitism in the Japanese serow inhabited in Aomori Prefecture.
