目前制备血吸虫免疫诊断用的抗原,常从人工感染家兔肝脏分离的虫卵提取抗原,或直接应用分离的虫卵和肝脏虫卵切片作为抗原。血吸虫卵的抗原性与虫卵的发育程度密切相关。刘绍沧曾对感染小白鼠的肝脏虫卵进行过逐日观察。而纯卵卵谱尚未见报道。我们对感染45d兔肝分离的纯卵 At present, antigens used for immunodiagnosis of schistosomiasis are often prepared, and antigens are often extracted from eggs isolated from artificially infected rabbits’ liver or directly isolated eggs and liver eggs are used as antigens. The antigenicity of the schistosome eggs is closely related to the development of the eggs. Liu Shaokang infected mice infected with the liver eggs were observed daily. The pure egg spectrum has not been reported. We are infected with pure rabbit egg 45d rabbit liver
