虫卵内毛蚴的可溶性分泌物可能具有双重生物学功能,使虫卵易于通过宿主组织和有助于孵化过程。分泌物中的部分抗原在宿主肝、肠等组织内还能诱发肉芽肿反应。为了确定可溶性虫卵抗原(SEA)在虫卵及毛蚴内分布的位置,作者等进行了下述研究。
Soluble secretions of the eggs of the miracidia may have dual biological functions that allow the worm to easily pass through the host tissue and aid in the hatching process. Some secretions in the host antigen in the liver, intestine and other organizations can induce granulomatous reaction. To determine the location of soluble egg antigen (SEA) distribution in eggs and miracidia, the authors performed the following study.
