用间接免疫荧光抗体法,对鼠体内两种类型卫氏并殖吸虫虫体抗原与宿主抗原做了检测。结果显示两类型童虫与感染同源卫氏并殖吸虫小鼠血清反应后,虫体抗原存在于体表皮层、肠管上皮细胞上;两类型童虫与兔抗鼠红细胞抗体血清反应后,主要在表皮层看到宿主抗原,荧光强度比虫体抗原所示为弱;三倍体型童虫的宿主抗原荧光反应有52.6～60％呈(++),而二倍体型大部只是(+)反应;这种荧光强度的差别在非免疫状态所获的童虫切片上也被看到。
Indirect immunofluorescence antibody method was used to detect two kinds of Paragonimus westermani antigen and host antigen in mice. The results showed that two kinds of schistosomiasis and homologous to infected Paragonimus westermani mouse serum response, the presence of antigen in the body surface epithelial cells, intestinal epithelial cells; two types of schistosomiasis and rabbit anti-rat erythrocyte antibody serum reaction, the main The host antigen was seen in the epidermis and the fluorescence intensity was weaker than that of the parasite antigen. The fluorescence of the host antigen of the triploid Schistosoma japonicum was (++) from 52.6 to 60%, while the diploid type was only (+), Reaction; this difference in fluorescence intensity was also seen on the schistosomal slices obtained in nonimmunized state.
