SUB-UNIFIED VACCINE AGAINST CIRCOVIRUS OF PIGS TYPE 2 (PCV2)

摘要

The present invention relates to an immunogenic composition against swine circovirus type 2 (PCV2) containing an antigenic peptide. The antigenic peptide is an open-reading arginine-enriched peptide 2 (ORF2) from PCV2 and / or a recombinant chimeric protein, which is a construct from an arginine-enriched peptide from ORF2 from PCV2, PE peptide and the KDEL signal peptide. The amount of arginine of the arginine-rich peptide from ORF2 from PCV2 is no more than half the amount of arginine enriched in the arginine domain at the N-terminus of ORF2 from PCV2.
