THE PRESENCE OF ANTIBODIES AGAINST PSEUDORABIES VIRUS IN WILD BOARS (SUS SCROFA) IN KOREA.

The control and elimination of pseudorabies (PR) is one of the most important goals in the pig industry. After the first PR outbreak in Korea in 1986, all pigs infected with PR virus (PRV) were removed, and a vaccination program for pigs was implemented. No PR has occurred in Korea since 2010, and vaccination was discontinued after 2013. Information on the seroprevalence of PRV in pigs, including wild boars (Sus scrofa), is important for evaluating the PR status in a country. In this study, 2.65% (28/1057) of the wild boars tested had antibodies against PRV in 2018, indicating that PRV has been circulating continuously in the wild boar population in Korea. Effective means should be implemented to prevent the transmission of PRV between wild and domestic pigs, because the wild boar is a potential reservoir host for PRV.
