- Cause Seasonal outbreaks of ordinary influenza arise as a result of influenza viruses undergoing minor genetic changes known as antigenic drift. 普通流感的季节性爆发,是由流感病毒出现称为抗原漂移的轻微基因变异所引起。
- The surface antigens of influenza viruses undergo frequent changes. Such changes can be minor called antigenic drift or major called antigenic shift. 流感病毒的表面抗原会常常改变,这些改变有时较小,称为抗原漂移antigenic drift,有时则较大,称为抗原转移antigenic shift。
- Part of these changes are due to antigenic drift,alterations caused by spontaneous mutation,producing minor changes in the antigenic structure of hemagglutinin. 抗原漂流为血凝素抗原结构微小变异 ,抗原突变为病毒在自然界进行基因重组。
- They observed that antigenic drift was more punctuated than genetic evolution, and genetic changes sometime had a disproportionately large antigenic effect. 此发现显示抗原性演化比基因演化更具有不连续之跳跃性，且基因序列上的改变有时会造成不等价之钜大抗原性影响。
