Sažetak
The insoluble immune complexes (ICs) were prepared under the conditions of double immunodiffusion in gel, using the suspension of the ultrasound treated PK 15 cell line infected with porcine parvovirus (PPV) containing both viral particles and viral proteins, as well as pig or rabbit anti PPV polyclonal immune sera. The immunodiffusion performed in an agarose gel allows only viral subunits with a molecular mass equal to or less than 1000 KKD, rather than the viral particles, to diffuse through the gel and reach the point where the immunoprecipitate is to be formed. The immunoprecipitation under the conditions of the diffusion ensures the optimal, i.e., equimolar ratio of both immunoprecipitating components, antibody/antigen in the IC. The sodium dodecyl sulfate polyacrylamide gel electrophoresis and the Western blot analyses showed the ICs were composed of two proteins, a protein which molecular mass corresponded to the VP2 of the PPV and a protein with a molecular mass of the IgG. This suggests that the ICs are mainly composed of the VP2 antigen and IgG class antibodies. The potency of the IC vaccines prepared in the form of a water in oil in water emulsion (WOWE) was compared with that of a commercially available, inactivated oil vaccine. The vaccination of gilts, 6 weeks before mating, with the IC containing allogeneic pig antibodies, resulted in the development of high and long lasting anti PPV antibody titers, similar to those generated by the licensed vaccine (probability > 0.01). The content of the virus material administered by the IC was more than twice lower than that in the licensed vaccine. Neither systemic nor local reactions were observed in the gilts during the period of the trial with the IC vaccine. The number of viable piglets per litter varied between 9 and 12 and no signs of the PPV infection were detected. Rabbits were used as one of the alternative laboratory animal models accepted for the testing of the vaccine against the PPV. The rabbit humoral immune response generated by the IC containing the allogeneic antibodies was higher than that generated by the ICs containing the xenogeneic pig antibodies. It was similar to that generated by two times higher content of the virus material administered by a commercially available vaccine. The IC based vaccines belong to non replicating, subunit vaccines which are both ecologically convenient and the safest vaccines of all.
