We report here the complete genomic sequence of a novel Newcastle disease virus (NDV) strain, egret/China/Guangxi/2011, isolated from an egret in Guangxi Province, southern China. A phylogenetic analysis based on a fusion gene comparison with different NDV strains revealed that egret/China/Guangxi/2011 was phylogenetically close to genotype VIIa NDV, and the deduced amino acid sequence was (112)R-R-R-K-R-F(117) at the fusion protein cleavage site. The whole nucleotide sequence had the highest homology (93.3%) with the sequence of strain chicken/Sukorejo/019/10 (GenBank accession number HQ697255). This study will help us to understand the epidemiology and molecular characteristics of Newcastle disease virus in a migratory egret.
我们在此报告一株新型新城疫病毒(NDV)株——白鹭/中国/广西/2011 的完整基因组序列,该病毒株从中国南方广西省的一只白鹭中分离得到。基于融合基因与不同 NDV 株比较的系统进化分析表明,白鹭/中国/广西/2011 株与基因型 VIIa NDV 亲缘关系较近,其融合蛋白裂解位点的推导氨基酸序列为(112)R-R-R-K-R-F(117)。整个核苷酸序列与毒株 chicken/Sukorejo/019/10(GenBank 登录号:HQ697255)的同源性最高(93.3%)。本研究将有助于我们了解迁徙白鹭中新城疫病毒的流行病学和分子特征。
