Results After six passages in BHK-21 cells, cytopathic effect was observed by microscopy. The rescued virus was rejuvenated once in unweaned mice, and then came back to cell passage. We found that the poly tract of rescued virus was shortened when the virus was passaged twice in BHK-21 cells. Although the data of LD50 in mice and TCID50 in BHK-21 cells showed that the virulence and infectivity of genetic engineering viruses were lower than its parental virus, no significant difference was observed between the genetic engineering viruses with the different length poly tract.

我们发现，基因工程毒在BHK-21上连续传代至第6代时，可见明显的致细胞病变效应(cytopathic effect，CPE)；在经过一代乳鼠接种之后再重新适应到BHK-21细胞的过程中，poly区段出现了缩短现象；乳鼠致病性试验和BHK-21细胞TCID50测定结果表明，尽管基因工程毒与母本毒相比毒力偏低，但含有不同长度poly的基因工程毒之间并无显著差异。
