摘要:

为了解牛肠道病毒(bovine enteroviruses,BEV)的分子特征和遗传特性,进一步研究病毒的毒株差异与分子流行病学,设计5对特异性引物,应用PCR扩增与序列测定技术,对BEVHeN-B78株(EV-E)和HeN-YR91株(EV-F)的全长基因组序列进行扩增、序列测定,将序列拼接校对后获得2株BEV的全基因组序列,并分析其同源性。结果表明,BEV HeN-B78株(登录号MN598013)基因组序列全长为7 453 nt,其中编码区全长 6 523 nt,5'UTR 长812 nt,3'UTR长118 nt。BEV HeN-YR91(登录号MN598018)株基因组序列全长为7 460 nt,其中编码区全长6 502 nt,5'UTR 长825 nt,3'UTR 长 133 nt。全基因组序列的同源性分析显示,HeN-B78株与其他EV-E参考株的相似性为75.9%~88.0%;HeN-YR91株与其他EV-F参考株的同源性为74.6%~82.4%。病毒分离株的全基因组、VP1~VP4、2B、2C、3A~3D基因的系统进化树分析结果均显示,HeN-B78株与其他EV-E处于同一分支,而HeN-YR91株与EV-F处于同一分支。综上,河南省牛场存在E种和F种两种肠道病毒感染,丰富了国内牛肠道病毒的基因库。

Abstract:

This study aimed to investigate the molecular and genetic characteristics of bovine enteroviruses (BEV) and further explore their features and molecular epidemiology. Five pairs of specific primers were designed to amplify and sequence the full-length genomes of the BEVHeN-B78 (EV-E) and HeN-YR91 (EV-F) strains using PCR. After sequencing, the full genomes were assembled, proofread, and analyzed for homology. The results showed that BEVHeN-B78 genome was 7 453 nt long, with a coding region of 6 523 nt, a 5' untranslated region (UTR) of 812 nt, and a 3'UTR of 118 nt. The HeN-YR91 genome was 7 460 nt, with a coding region of 6 502 nt, a 5'UTR of 825 nt, and a 3'UTR of 133 nt. Homology analysis showed that the HeN-B78 strain shared 75.9% to 88.0% similarity with species E, while HeN-YR91 shared 74.6% to 82.4% similarity with species F. Phylogenetic analysis of the whole genome and the VP1-VP4, 2B, 2C, and 3A-3D gene regions, confirmed that the HeN-B78 strain clustered with EV-E and the HeN-YR91 strain with EV-F. In conclusion, this study confirms the presence of bovine enterovirus species E and F in cattle farms in Henan Province, contributing valuable data to GenBank database of BEV in China.
