Peptide inducing formation of neutralizing antibodies, immunogenic preparation, vaccine, synthetic antibody, diagnostic kit, use thereof and testing method of PRRS virus occurrence in pigs
The invention provides antigenic sites of PRRSV isolates. The antigenic sites are neutrahzmg, conserved, non-conserved and conformational, can elicit axntihodiee and are found on protein GP 4 and N encoded by ORF4- and ORF7 of PRRSV. The peptide sequences identified by the sites can be incorporated in vaccines directed against PRRS and in diagnostic tests for PRRS. Also, discriminating tests can be developed that can be used next to marker vaccines in programs designed to eradicate PRRS from pig herds.
