In order to compare the homology of the gene encoding VP2 between MDPV-Q and MDPV which was registered in the GenBank, also in order to find out changes of the VP2 gene and the immuno-genicity between the wild-strain MDPV-Q and the attenuated strain MDPV-26 which derived by continued passage of virulent wild-type in muscovy duck embryo, a pair of primer (LHMP7/LHMP8) was designed. The upper one LHMP7 and the lower one LHMP8 corresponded to the MDPV-specific nucleotides sequence 2885-2900 and 4618-4604 respectively, according to the MDPV nucleotide sequence databases. The length of the sequence embraced by the primers was 1734bp.

为了获取这一基因片段与国外分离株进行同源性比较，同时也为了了解MDPV强、弱毒株VP2基因之间的异同关系，及其免疫原性的变化规律，通过DNA重组技术，设计了一对引物LHMP7／LHMP8，该对引物选取位于2885～2900及4618～4604的两段序列，跨幅为1734bp，并在这两条引物中分别加入两种限制性核酸内切酶SacⅡ和KpnⅠ的酶切位点，分别对MDPV-Q和由该株病毒经人工致弱后得到的MDPV-26株进行PCR扩增，并将PCR产物克隆到pMD18-T载体上，分别得到二个重组子：pMD18-T—M-Q VP2和pMD18-T-M-26 VP2。

The amplified band from M131 was sequenced and then aligned with the sequence of avr-Pila gene. The result was that the sequence was 98% homologous to one fragment of avr-Pita sequence, but the integration site was not within this fragment.

将M131的扩增片段测序后得到长度为1057bp的序列，并且将所测序列和已知的avr-Pita一段序列比较发现达98％的同源，即该序列为无毒基因的某一段序列，但插入的位点并不在所扩增片段内。
