Abstract

Field isolates of suid herpesvirus 1 (Aujeszky's disease virus) from Poland and Hungary were identified by restriction fragment pattern analysis as derivatives of attenuated vaccine strains. The Polish isolates were found to be related to the BUK-TK-900 strain (Suivac A) which is widely used as a live vaccine in Poland, and the Hungarian isolates were related to the Bartha K-61 vaccine strain widely used in Hungary. Pigs experimentally infected with derivatives of BUK-TK-900 or BUK-TK-900 itself were found to develop gI-antibodies, while pigs infected with derivatives of Bartha K-61 showed a gI-negative response.
