Abstract
Forty 5-month old swine were treated with immunomodulating Propionibacterium avidum KP-40 (PA) and/or immunized with live attenuated Aujeszky's disease (AD) virus vaccine (SuivacA); 8 weeks later all animals were infected with virulent AD viruses (NIA-3). Seven of 10 swine vaccinated without PA developed mild/moderate symptoms of infection with 3- to 5-day fever and a temporary halt in weight gain. Application of PA together with the vaccine lowered the morbidity rate, shortened the period of fever and speeded recovery. Only low levels of virus-neutralizing IgG antibodies were found in vaccinated swine and application of PA did not influence antibody titers.
