Abstract

The outbreak of viral encephalomyelitis (Talfan disease) in suckling piglets was diagnosed pathologically for the first time in Korea. The clinical signs of affected sucklings were very high morbidity without death, and fever ($39^{circ}C$ or higher) with incoordination of the rear limbs and paresis, while no specific gross lesions were observed at autopsy. Histopathological changes were confined to the nervous system, and were of the nature of a nonsuppurative and nondemyelinating encephalomyelitis which is usual for the viral encephalitis. It was characterized by perivascular cuffing, meningitis, neuronal degeneration, neuronophagia and glial nodules in the brain and spinal cord.
