中文摘要：

免疫预防是控制棘球蚴病经济、快速且有效的方法。近年来棘球蚴病的免疫学和疫苗研制方面均取得了很大进展，分子疫苗成为预防包虫病流行较理想的方法。其中细粒棘球绦虫EgA31疫苗是一有希望的疫苗候选分子，本文从EgA31抗原的基因结构和免疫特性等方面介绍了其分子生物学特征。

英文摘要：

Immunoprophylaxis is an economical, quick and effective method to control echinococcosis. In recent years, great progress has been made in ＇both immunology and vaccine development of echinococcosis. The molecular vaccine becomes to be an ideal method to prevent the epidemic of hydatid disease, and the vaccine EgA31 is one of promise candidates for the vaccine development. The molecular biological characteristic of EgA31 antigen including genetic structure and immune specificity is reviewed in this paper
