Toxoplasmin--a highly purified extract from the protozoa Toxoplasma gondii propagated in mice--was tested for the presence of the mouse species-specific antigens by immunodiffusion in agar gel and by PCA test. Neither test gave positive reaction. It was concluded therefore that Toxoplasmin Sevac used for the detection of dermal hypersensitivity to toxoplasma antigens in humans does not contain any detectable contamination by mouse species-specific antigens within the limits of sensitivity of both methods used.
弓形虫素——一种从在小鼠体内繁殖的原生动物刚地弓形虫中高度纯化的提取物——通过琼脂凝胶免疫扩散和PCA试验检测其中是否存在小鼠种属特异性抗原。两种试验均未产生阳性反应。因此得出结论，用于检测人类对弓形虫抗原皮肤超敏反应的Sevac弓形虫素，在所使用的两种方法的灵敏度范围内，未检测到任何被小鼠种属特异性抗原污染的情况。
