Prototype strains of the influenza A (H3N2) virus can be arranged on a gradient showing the degree of the antigenic drift which the haemagglutinins of the strains have undergone. The demonstration of fine antigenic differences is based on an antiserum absorption test which allows a detailed antigenic analysis of strains. The gradient provides information on variation in strains occurring in different geographical areas and its use may be helpful in differentiating between introduced strains and locally developing variants.
甲型(H3N2)流感病毒的原型毒株可以排列在一个梯度上,以显示这些毒株的血凝素所经历的抗原漂移程度。细微抗原差异的证明基于抗血清吸收试验,该试验可对毒株进行详细的抗原分析。这个梯度提供了不同地理区域毒株变异的信息,其应用可能有助于区分传入毒株和本地产生的变体。
