近年来观察证明,流感经常发生流行波动与原始毒株的消失和漂流变异的传播有关,这是由于病毒抗原部分发生改变的结果。并指出,在新的漂流变异株的血球凝集素里含有新的决定因素,这对于开始一个流行周期的原始型毒株来讲,决定因素的性质是在进行性地下降。因此,根据流感A/香港/1/68(H_3N_2)原始毒株特点,无论在发生的时间上,或在被最近的漂流变异株取代以后,对于追踪居民中免疫学反应的发生是有意义的,为了这个目的,我们得到了关于流感病毒A/香港/1/68(H_3N_2)抗体存在的分析材料。用
In recent years, it has been observed that the frequent fluctuations of influenza are related to the disappearance of the original strain and the spread of drifting variation due to the change of the antigenic part of the virus. And pointed out that there is a new determinant in the hemagglutinin of the new drifting mutant, which declines progressively for the virulent strain to begin a pandemic. Therefore, based on the characteristics of the original strain of influenza A / Hong Kong / 1/68 (H_3N_2), it is of interest to track the occurrence of immunological reactions among residents, both at the time of occurrence or after being replaced by the most recent drifting mutants For this purpose, we obtained analytical material on the presence of influenza A / Hong Kong / 1/68 (H_3N_2) antibodies. use
