CHEMICAL CHANGES, DNA CLOTHES OF THE HORSE TYPE AND EX-HORSE USES

摘要

This invention relates to a product of immunogenic polypeptide that is obtainable from the expression of clones of infectious chimeric DNA of the porcine cycle (PCV). This inventoror is also associated with corresponding vaccines and means of protection against viral infection or with PMWS inducedfrom PCV. The new chimeric infectious DNA clone is produced by the non-pathogenic PCV1 in which the ORF pathogen PCV2 replaces a non-pathogenic PCV1 genePreferably in the same position.
