应用ＥＬＩＢ技术观察旋毛虫肌蚴抗原（ＴｓＭＬＳＡ）与６种寄生虫病人血清的交叉反应。结果表明：ＴｓＭＬＳＡ中３１～１００ＫＤａ内的蛋白大部分可被急性血吸虫病人血清所识别，而慢性血吸虫病人血清仅识别其中的４４／４５，５１／５３，６２／６４及１００ＫＤａ蛋白；小于６０ＫＤａ者可与丝虫病、钩虫病、肺吸虫、蛔虫病和肝吸虫病人血清呈不同程度的交叉反应，以前三者为最明显；４５ＫＤａ蛋白可被部分正常人血清识别。提示，旋毛虫肌蚴抗原与多种寄生虫有共享成分，但与血吸虫的交叉可依据４组区带用以鉴别诊断此二种寄生虫病。
The ELIB technique was used to observe the cross-reactivity of the trichomonas laevis antigen (TsMLSA) with the sera of six parasite patients. The results showed that most of the proteins in the range of 31-100 kDa in TsMLSA could be recognized by the serum of acute schistosomiasis patients, whereas the serum of chronic schistosomiasis patients only recognized 44/45, 51/53, 62/64 and 100 kDa proteins; those less than 60 kDa With the filariasis, hookworm disease, paragonimiasis, ascariasis and paragonimiasis serum showed varying degrees of cross-reaction, the former three were the most obvious; 45KDa protein can be recognized by some normal human serum. Tip, Trichinella anti-sporozoite antigen and a variety of parasites have shared components, but the cross with the schistosome can be based on the four groups of zones for the differential diagnosis of the two parasitic diseases.
