The results showed that the canary pox virus could adapt to chicken embryo and cause canary death after passage 3 generations. The pox virus had no virulence for canary after passage 8 generations. The virus of 13th generation had no virulence reversion through inoculating canary three times. 结果表明:金丝雀痘病毒经鸡胚盲传3代后能适应鸡胚并致死金丝雀,8代后无致病性,13代毒快速通过本动物3次无返强现象。
