Recombinant antigenic protein for diagnosis of porcine reproductive and respiratory syndrome and use thereof

摘要

The present invention evaluates immune formation and immune levels against porcine genital and respiratory syndrome viruses, and at the same time detects specific antibodies derived from two genotypes of the North American and European porcine genital and respiratory syndrome viruses. The present invention relates to a novel recombinant antigen protein capable of simultaneously diagnosing the infection of a syndrome virus and its diagnostic use. Antigen proteins for diagnosing North American and European porcine genital and respiratory syndrome viruses of the present invention include both North American PRRSV and European PRRSV-derived proteins, and also include variable amino acid sequences for each genotype. It is possible to diagnose both North American and European PRRSV antibodies simultaneously, and it is possible to rapidly and highly efficient PRRSV immunity evaluation by improving the specificity of PRRSV in a PRRS negative maintenance farm including a pig farm. It can be very useful to minimize the economic damage caused by.
