The activation of poliomyelitis virus from a "neutral" virus-antibody mixture by the addition of non-infectious virus is described. The phenomenon was demonstrated in tissue cultures using both Petri dishes and roller tubes. The reaction was found to be type-specific and a relationship between antigen dilution and number of plaques counted was established. The relative potency of vaccine preparations determined in this system was found to be comparable to their relative potency in respect to protection-inducing activity in mice.
本文描述了通过添加非感染性病毒,将脊髓灰质炎病毒从“中和”的病毒-抗体混合物中激活的过程。该现象在使用培养皿和滚瓶的组织培养中得到了证实。发现该反应具有型特异性,并建立了抗原稀释与所计数的蚀斑数量之间的关系。在该系统中测定的疫苗制剂的相对效力被发现与其在小鼠中诱导保护活性方面的相对效力相当。
