We first report avipoxvirus (APV) infection and an isolate named APV/03/2016 from a red-flanked blue robin () captured at Songhua Lake Scenic Area in Jilin City (Jilin Province, China) on March 24, 2016. The partial sequence of the 4b core protein gene and DNA polymerase gene of APV/03/2016 suggests that the virus belongs to the subclade B1 cluster of clade B (canarypox virus). The BLAST results showed the highest similarity of the two genes with the Pacific shearwater-isolated strain SWPV-2 (KX857215), canarypox virus strain D98-11133 (GQ487567), canarypox virus strain ATCC VR-111 (AY318871), avipoxvirus Mississippi isolate P89 (KC018048), and avipoxvirus Wisconsin isolate P92 (KC018051). The results indicate that APV/03/2016 is a canarypox-like virus. These findings demonstrate the continuous emergence of new APV hosts such as red-flanked blue robins and suggest that monitoring of APV circulation and evolution should be strengthened for conservation.
我们首次报告了2016年3月24日在中国吉林省吉林市松花湖风景区捕获的一只红胁蓝尾鸲身上感染禽痘病毒（APV）以及分离出的名为APV/03/2016的毒株。APV/03/2016的4b核心蛋白基因和DNA聚合酶基因的部分序列表明，该病毒属于B进化枝（金丝雀痘病毒）的B1亚分支。BLAST结果显示，这两个基因与太平洋鹱分离株SWPV-2（KX857215）、金丝雀痘病毒株D98-11133（GQ487567）、金丝雀痘病毒株ATCC VR-111（AY318871）、禽痘病毒密西西比分离株P89（KC018048）和禽痘病毒威斯康星分离株P92（KC018051）的相似性最高。结果表明，APV/03/2016是一种类似金丝雀痘的病毒。这些发现证明了红胁蓝尾鸲等新的APV宿主不断出现，并表明为了保护目的应加强对APV传播和进化的监测。
