With rabbit antiserum against ECP of reference strain JEL4,ECPs of 25 Et strains were detected by Dot-ELISA; additionally,alI strains had been detected both on their virulent factor Excellular Products, including the hemolysin and extracellular protease, and on their pathogenicity to mice and Xiphophorus helleri.

以Et强致病株JEL4的胞外产物ECP为抗原制备兔抗血清，用于Dot-ELISA检测25株Et的ECP，同时对Et的溶血素和胞外蛋白酶进行检测，结合小鼠和剑尾鱼的致病性试验。

Pike protein consists of S1 and S2 subunit. S1 is head and S2 is rod-shape part, intermolecular effort can bind each other. S1 can bind with host cell epimembranal acceptor. S2 can fix integral Spike protein on the cellular membrane and mediate cell-fusion with virus and host cell. There are significant antigen determinant of virus in Spike protein, genic heterogenesis can effect viral pathogenicity. SARS-CoV Spike protein, which has 23 pieces larvaceous glycosylation sit, consists of 1256 amino acid. Its N-terminals and C-terminals is corresponding conservative.

蛋白是I型膜糖蛋白，介导病毒与宿主细胞膜上的受体结合并与宿主细胞膜相融合。S蛋白由S1和S2两个亚基组成。S1形成球状部分，S2形成棒状部分，两者之间通过分子间的作用力相互结合。S1能与宿主细胞上的受体结合，S2可把整个S蛋白固定在细胞膜上，并介导病毒包膜与宿主细胞膜融合。S蛋白上有重要的病毒抗原决定簇，S基因的突变会影响病毒的致病性。

The mutant decreased in growth rate, and lost in pathogenicity to wheat seedling and in homothallism as compared with those of parent isolate.

该突变株与亲本菌株相比，生长速率下降、致病性和同宗配合能力丧失。

Nowadays, research on the interrupt genes of such slow-growth mutants is seldom, either does not the research on the relationship between pathogenicity and hypha development.

目前，菌落生长缓慢突变体的研究和该类突变体相关基因的报道较少，菌丝生长与致病性的关系的研究也不系统。

Objective To understand the infectivity and pathogenicity of the plasma of hepatitis E virus viremia to primate animals.

目的 了解戊型肝炎病毒核酸阳性血浆对灵长类动物的感染性和致病性。
