Genotype 8 of yellow head virus (YHV-8) was identified recently, but the complete genome sequence of this new genotype has not been reported. In this study, the complete genome of YHV-8 isolate 20120706 collected from Hebei Province of China in 2012 was sequenced. It was found to be 26,769 nucleotides (nt) in length, including a 20,060-nt open reading frame 1 (ORF1), a 435-nt ORF2, and a 4971-nt ORF3. Isolate 20120706 shared 79.7-83.9% nucleotide sequence identity with all seven of the complete genome sequences of YHV that have been reported so far. The topology of a phylogenetic tree constructed based on the ORF1b region clearly showed that strain 20120706, together with five other YHV-8 strains isolated in China, represents a new genotype of YHV. This is the first report of the complete genome sequence of a YHV-8 isolate, and the 20120706 isolate will be useful for further analysis of the epidemiology and evolution of YHV-8.
黄头病毒8型（YHV - 8）是最近才被鉴定出来的，但这种新基因型的完整基因组序列尚未见报道。在本研究中，对2012年从中国河北省采集的YHV - 8分离株20120706的完整基因组进行了测序。结果发现其长度为26,769个核苷酸（nt），包括一个20,060 nt的开放阅读框1（ORF1）、一个435 nt的ORF2和一个4971 nt的ORF3。分离株20120706与目前已报道的所有7个YHV完整基因组序列的核苷酸序列同一性为79.7% - 83.9%。基于ORF1b区域构建的系统发育树拓扑结构清楚地表明，菌株20120706与在中国分离的其他5个YHV - 8菌株一起，代表了YHV的一种新基因型。这是YHV - 8分离株完整基因组序列的首次报道，20120706分离株将有助于进一步分析YHV - 8的流行病学和进化情况。
