Abstract

Aujeszky's disease virus(ADV) was inoculated intranasally into the Korean native goats to investigate pathological findings and pathogenesis of ADV infection by using of histological and immunohistochemical methods and in situ hybridization(ISH). Clinical signs of salvation, pyrexia, pruritus and staggering were followed by death with five days after inoculation, Pathoanatomical findings were edema of the lung and the urinary bladder with hemorrhage and congestion, petechial hemorrhages on the endo-and epicardium, renal congestion, moderate splenomegaly and cystic edema. Main microsocpic lesions observed in all infected goats were confined to the CNS and charcterized by perivascular cuffing with lymphocytes and macrophages, focal gliosis, neuronal degeneration and necrosis, and intranuclear inclusion bodies in the neurons and glial cells. Positive reactions to ADV were detected more frequently in the nuclei than in the cytoplasms of infected nerve cells in the CNS by immunohistochemistry and ISH. Frequenctly localized sites of ADV in the CNS were olfactory bulb, prietal cortex, callosal sulcus and corpus callosum. Positive reactions were also detected in the tonsillar epithelium, and alveolar macrophage and sloughed epithelium of the lung.
