Abstract:
One strain of PRRSV was isolated from tissue of piglets died of obvious respiratory syndrome and high fever.It was identified as a strain of American type PRRSV by serological test and gene sequencing.According to American type PRRSV VR-2332,we designed 3 pairs of primers to aim directly at N gene,GP5 gene and variation sequence of NSP2.The results of sequence analysis indicated a discontinuous deletion of 30 amino acids in nonstructural protein 2 (NSP2).N and GP5 gene is conservative relatively.
