Protoplasmic extracts isolated from four different species of mycobacteria contained common and species-specific antigens. Both the common and the specific antigens were involved in the elicitation of the tuberculin reaction in sensitized guinea pigs. The elimination of the common antigens from the extracts by means of cross absorption with heterologous mycobacterial antibodies led to preparations which, at the doses used in this study, elicited a cutaneous reaction in animals sensitized with the corresponding strains only. Moreover, the tuberculin activity of the common antigens was about the same in animals sensitized either with homologous or heterologous strains.
从四种不同分枝杆菌物种中分离出的原生质提取物含有共同抗原和物种特异性抗原。共同抗原和特异性抗原都参与了致敏豚鼠结核菌素反应的引发。通过用异源分枝杆菌抗体进行交叉吸收从提取物中去除共同抗原，得到的制剂在本研究使用的剂量下，仅在对相应菌株致敏的动物中引发皮肤反应。此外，共同抗原在对同源或异源菌株致敏的动物中的结核菌素活性大致相同。
