摘要: 合成一对猪Ⅱ型圆环病毒(PCV-2)ORF1基因特异性引物,对分离到的郑州分离株(ZZ株)猪圆环病毒PCV-2型的ORF1 基因进行了扩增,经测序后,将所测序列与已公布的35株PCV-2 ORF1序列进行同源性比较,并绘制系统发育进化树。结果显示,所测毒株间的ORF1基因核苷酸同源性为97.3~100%;进化树分析表明各分离毒株ORF1基因在进化上比较保守。同时对PCV-2 OFR1部分功能进行分析,发现该基因蛋白具有良好的抗原性

Abstract: The ORF1 gene was amplified from from ZZ strain of PCV-2 respectively using the primers designed according to the PCV-2 OFR1 sequence published in Genbank. The nucleotide sequence data of PCV-2 ORF1 gene was analyzed by comparing with that of other PCV-2 ORF1 gene sequence. The results indicated that the nucleotide homology of all selected PCV-2 ORF2 genes was 97.3 %~100 %.Meanwhile, several conserved founctional domains were discovered in PCV-2 ORF1 gene and found the protein translated by PCV2-ORF1 gene having well immunogenicity.
