弓形虫抗原分型,迄今未见报告,其原因与弓形虫滋养体的纯化较难,各种常用的免疫学和血清学方法,包括染色试验,补体结合试验、间接血凝试验、免疫荧光技术、ELISA以及皮内试验等检查不同来源的虫株,均未发现有明显而规律的抗原差异。直到1987年ware和Kapser使用免疫印渍法才发现3株弓形虫有抗原差异。我们证明这些差异,在株间不规律,变化较大,故不适于抗原分型。我们发现纯化的弓形虫滋 Toxoplasma antigen typing has so far not been reported, the reason for the purification of Toxoplasma trophozoites more difficult, a variety of commonly used immunological and serological methods, including staining, complement fixation test, indirect hemagglutination test, immunofluorescence , ELISA and intradermal test to check the different origin of the worm strains, were found no significant and regular antigen differences. Until 1987, ware and Kapser using immunofluorescence method to find three toxoplasmosis antigen differences. We show that these differences in the strains between the irregular, great changes, it is not suitable for antigen typing. We found purified Toxoplasma gondii
