Constancy of Aujeszky's field virus antibody titres in sows repeatedly vaccinated with a gI-negative vaccine.
A breeding herd repeatedly vaccinated with a gI-deleted vaccine was regularly tested serologically for Aujeszky's field virus antibodies over a period of up to 35 months. Of the 100 sows tested, 18 animals reacted positively with constant titers during the whole period of the investigation. On the other hand, there was no serological evidence that any of the contact animals contracted field virus infection.
