摘要: 用RT-PCR方法分段扩增出猪繁殖障碍与呼吸道综合征病毒(PRRSV) FZ株的5条cDNA片段,分别克隆到pMD-18T载体并进行测序,按顺序将这些序列进行拼接得到FZ株ORF2-7编码框序列,测序结果表明该序列长度为3272bp,与BJ4株、VR2332株、CH-1a 株和HB-1株核苷酸同源性分别为99.1%、98.9%、93.2%和93.2%。

Abstract: 5 cDNA fragments of porcine reproductive and respiratory syndrome virus(PRRSV) FZ strain were amplified by RT-PCR, cloned into pMD-18T vector respectively and sequenced. ORF2-7 nucleotide sequence of genome of PRRSV FZ strain was obtained by spicing sequence of each fragment in order. The results showed that this sequence was 3272 bp in length. Compared with BJ-4、CH-1a and HB-1strain,the homology was 99.1%、98.9%、93.2% and 93.2% respectively.
