摘要: 应用免疫印斑试验观察日本血吸虫成虫蛋白与感染日本血吸虫病人和鼠血清的反应证实:日本血吸虫和曼氏血吸虫具有相同的31/32KD诊断蛋白;两者均来源于成虫肠管:与抗血吸虫单克隆抗体的反应基本相同。但是,两种血吸虫蛋白至少有一个抗原决定簇不同。日本血吸虫诊断蛋白与血吸虫病人和其他寄生虫病患者血清检测结果,证实了血吸虫成虫31/32KD蛋白可应用于日本血吸虫病的血清学诊断。

Abstract: Sera of schistosomiasis japonica patients and of S. japonicum-infected mice were tested in immunoblots for their reactivity with adult schistosome proteins. We demonstra-ted the existence in S. japonicum of proteins sharing the diagnostic antigenicity of S. mansoni proteins, with approximately the same molecular weight of 31/32 KD, their reactivity with monoclonal antibodies and association with the schistosome gut. The proteins are, however, different between the two species at least in respect to one epitope and the relative mobility of one component. We confirmed the specificity of S. japonicum proteins by testing with sera of patients with other parasitic diseases. The data add support to the possible application of 31/32 KD schistosome proteins for serodiagnosis of sehistosomiasis Japonka.
