目的了解浙江省麻疹野毒株的抗原性变异状况。

2·Conclusions Wild-type measles virus prevailing in Zhejiang Province has appeared significant antigenic variation.

结论浙江省麻疹野毒株已出现明显的抗原性变异。

3·The antigenic variation of flu virus is closely related to the epidemic situations, the precaution, and the control of flu.

流感病毒抗原变异与流感的流行大小、预防、控制密切相关。

4·The different reactive profile of the MAbs with the NDV strains demonstrated the presence of antigenic variation on the HN protein.

单抗与病毒之间的反应差异性表明HN蛋白上的部分抗原表位存在着较明显的变异。
