At first, study on antigenic variation in trypanosoma evansi from a clonal stock in rabbit was carried out
首先進行的是伊氏錐蟲一個單克隆株在5隻兔體內連續抗原變異的研究。 -
The result shows that a vvibdv strain was obtained, the above work lay a important role for further studying on the molecular biological mechanism of antigenic drift and virulence variation of ibdv, molecular epedimiology, it also provided the basis for recombinant and gene deleted vaccine of ibdv
本實驗可以幫助我們進一步探討ibdv抗原性漂移和毒力變化的分子生物學機制，追溯ibdv的起源，理解病毒的傳播方式。同時也為研製開發基因重組疫苗和缺失疫苗打下一定的基礎。 -
The result shows that the high degree of homology of e2 sequences and 426 residues amino acid sequences existed in the strain hclv, hcv - jn, hcv - yc, fc and the epitopes between the four strains are not variable obviously by analysising the variation of some main amino acid residues substitutions of e2 major antigenic domains, confirming initially immunization with hcv vaccine strain can resist challenging of field strains
結果發現， hclv與fc間核苷酸及氨基酸序列的同源性分別為98 . 3 、 99 . 2 ；兩個野毒株與hclv和fc株之間的同源性也分別在98以上，與alfort株的同源性最低，分別在83 、 89左右。據此，可推測hclv 、豬瘟野毒株和c株之間的e2基因序列及氨基酸序列無明顯差異。
