摘要： The present invention relates to infectious DNA clones, infectious chimeric DNA clones of porcine circovirus (PCV), vaccines and means of protecting pigs against viral infection or postweaning multisystemic wasting syndrome (PMWS) caused by PCV2. The new chimeric infectious DNA clone and its derived, avirulent chimeric virus are constructed from the nonpathogenic PCV1 in which the immunogenic ORF gene of the pathogenic PCV2 replaces a gene of the nonpathogenic PCV1, preferably in the same position. The chimeric virus advantageously retains the nonpathogenic phenotype of PCV1 but elicits specific immune responses against the pathogenic PCV2. The invention further embraces the immunogenic polypeptide expression products. In addition, the invention encompasses two mutations in the PCV2 immunogenic capsid gene and protein, and the introduction of the ORF2 mutations in the chimeric clones.

摘要： The present invention relates to a method for detecting and differentiating PCV infections in a biological sample taken from a pig which involves amplifying a fragment from an extracted nucleic acid; digesting the fragment with a suitable restriction enzyme such as the unique NcoI restriction enzyme; forming a restriction fragment length polymorphism pattern; and then detecting the presence or absence of a PCV isolate. The invention further concerns the new oligonucleotide primers for differentiating PCV infections comprising a nucleotide sequence selected from the group consisting of MCV1 having a nucleotide sequence set forth in SEQ ID NO:1 and MCV2 having a nucleotide sequence set forth in SEQ ID NO:2. Moreover, this invention provides a novel kit for detecting and distinguishing PCV infections that includes the new oligonucleotide primers and the suitable restriction enzyme.
