摘  要:
以鹅副粘病毒HZ株的基因组RNA为模板,采用RT-PCR技术扩增出F基因片段,然后将其克隆到pUCm-T载体中。经转化、筛选、酶切和PCR鉴定后,初步获得含鹅副粘病毒F基因的阳性克隆,并进行序列测定验证。结果表明,该基因由1 662个核苷酸组成,共编码553个氨基酸。与GenBank下载的9株参考毒株的F基因作同源性比较,发现HZ株与ZJ1、F48E9、Lasota等毒株的核苷酸同源性分别为98.3%、85.4%、82.7%;氨基酸同源性分别为97.8%、90.6%、88.1%。说明HZ株与经典的鸡新城疫病毒(NDV)在F基因上存在很大的差异,而与近年来的分离株亲缘关系较近。

摘  要:
The genomic RNA from purified GPV-HZ strain was extracted and used as a template for PCR.The fragment of the fusion gene was amplified by RT-PCR with the primers designed according to the sequence of NDV from Genbank and cloned into pUCm-T and sequenced.As a result,the ORF of fusion gene was 1662 bp in length,encoding 553 amino acid.By sequence comparison among HZ and ZJ1,F48E9 and Lasota strains,homologies of nucleotide sequence were 98.3%, 85.4% and 82.7% respectively.Homologies of the amino acid were 97.8%,90.6% and 82.7% respectively.The results indicated that the mutation on the F gene had varied largely,compared with classic NDV.
