Abstract

We surveyed the antibody titers in the slaughtered pigs by enzyme immunodiffusion method for the epidemiological distribution of Aujeszky's disease in Korea. And also we observed the clinical symptoms, histopathological findings and antibody titers by serologic neutralization test in experimental animals infected with Aujeszky's disease virus(ADV) isolated from Korea. The results of the experiments were summarized as follows. 1. We detected 2 pigs infected with ADV of 1000 in 1990 and 1 of 600 in 1991 by enzyme immunodiffusion method. 2. In histopathological findings of experimental animals inoculated ADV, the typical characteristics of Aujeszky's disease were not observed in pig, but edema and degeneration in the epidermis were observed in rats, vasculoendotheriosis, perivascular cuffing and cellular infiltration in the cerebrum were appeared in rabbits and perivascular cuffing and forcal infiltration of glial cells in the cerebrum were appeared in mice. 3. The increasing antibody titers(1 : 64) in the serological neutralization test were ascertained in 2 carrier pigs inoculated ADV. 4. Rabbits, mice and rats died all about 5 days after inoculation, but pigs and chickens didn't die. 5. In 1 cat and 2 rabbits inoculated with the Aujeszky's disease virus(ADV), the typical clinical findings of Aujeszky's disease were observed in rabbit, but not in cat and so we slaughtered without any signs of Aujeszky's disease.
