The preparation of complement-fixing antigens for the Coxsackie group of viruses (C virus) is described. This includes the manufacture of crude antigens, their subsequent treatment with protamine sulfate to remove non-specific interfering substances, and their concentration by ultracentrifugation. The plate complement fixation technique of Fulton and Dumbell is described in detail as it has been used for the Coxsackie viruses. Seven strains of C virus have been cross-tested in the plate complement fixation test and have been found to belong to six immunologically distinct types. The temporal pattern of complement-fixing antibodies in human beings infected with two types, Ohio-1 and Easton-2, respectively, has been studied. In the former the antibodies rise to a peak rather late in convalescence (3rd month) and in the latter, complement-fixing antibodies are already present at high levels in the acute phase serum. The problems of serodiagnosis are briefly discussed.
本文描述了柯萨奇病毒组(C病毒)补体结合抗原的制备方法。这包括粗抗原的制备、随后用硫酸鱼精蛋白处理以去除非特异性干扰物质,以及通过超速离心进行浓缩。详细描述了富尔顿和邓贝尔的平板补体结合技术,因为它已用于柯萨奇病毒。七种C病毒株在平板补体结合试验中进行了交叉检测,发现它们属于六种免疫上不同的类型。分别对感染俄亥俄-1型和伊斯顿-2型两种病毒的人类补体结合抗体的时间模式进行了研究。在前者中,抗体在恢复期后期(第3个月)才升至峰值,而在后者中,急性期血清中补体结合抗体已处于高水平。本文还简要讨论了血清学诊断的问题。
