RECOMBINANT PROTEINS FOR THE FUSION OF THE PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS AND ITS USE IN DIAGNOSIS

摘要

The recombinant fusion proteins comprise the nucleocapside proteins of the porcine reproductive and respiratory syndrome virus (PRRSV), which has been obtained both from a European isolate of PRRSV and from an American isolate, and which was fused to an amino-acid sequence derived from the system selected for the expression of said recombinant fusion protein either directly or through a union region formed by a small number of amino-acids. Said recombinant fusion proteins are appropriate to be used in diagnosing PRRSV.
