目的 对２ 株 Ｐ Ａ Ｇ Ｅ 图型相似的 Ｂ 组轮状病毒———成人腹泻轮状病毒（ａｄｕｌｔ ｄｉａｒｒｈｅａｒｏｔａｖｉｒｕｓ， Ａ Ｄ Ｒ Ｖ） 和大白鼠乳鼠腹泻轮状病毒（ｒａｔ ｄｉａｒｒｈｅａ ｒｏｔａｖｉｒｕｓ， Ｒ Ｄ Ｒ Ｖ） 主要基因的相关性进行研究。方法 Ｒ Ｔ Ｐ Ｃ Ｒ 扩增 Ａ Ｄ Ｒ Ｖ 第４ 、５ 、９ 三个基因的ｃ Ｄ Ｎ Ａ 全长拷贝，并获其ｃ Ｄ Ｎ Ａ 克隆。用 Ａ Ｄ Ｒ Ｖ第９ 基因末端引物 Ｒ Ｔ Ｐ Ｃ Ｒ 成功扩增了 Ｒ Ｄ Ｒ Ｖｄｓ Ｒ Ｎ Ａ，获得相对分子质量与 Ａ Ｄ Ｒ Ｖ 第９ 基因 Ｐ Ｃ Ｒ产物８１４ｂｐ 相等条带（ 暂称该 Ｒ Ｎ Ａ 模板为 Ｒ Ｄ Ｒ Ｖ 第９ 片段） 及其克隆。经 Ｄｉｇｏｘｉｇｅｎｉｎ 标记制备 Ａ Ｄ Ｒ Ｖ 第４ 、５ 、９ 及 Ｒ Ｄ Ｒ Ｖ 第９ 基因的ｃ Ｄ Ｎ Ａ 探针。用核酸点杂交、 Ｎｏｒｔｈｅｒｎ 杂交进行同源性比较。结果 获得 Ａ Ｄ Ｒ Ｖ 第４ 、５ 、９ 三个基因及 Ｒ Ｄ Ｒ Ｖ 第９ 基因的ｃ Ｄ Ｎ Ａ 克隆；用 Ａ Ｄ Ｒ Ｖ 第４ 、５ 、９ 及 Ｒ Ｄ Ｒ Ｖ第９ 基因４ 个ｃ Ｄ Ｎ Ａ 探针进行的点杂交和 Ｎｏｒｔｈｅｒｎ 杂交结果显示，在两病毒 Ｒ Ｎ Ａ 相应点和相应片段的位置上杂交信号都为阳性，阴性对照都为阴性。
Objective To investigate the effect of two groups of rotavirus of group B with the similar pattern of P A G E - adult diarrhearotavirus (ADRV) and rat diarrhea rotavirus (R D R V) major genes were studied. Methods RT-PCR was used to amplify full-length cD N A copies of the 4, 5, 9 genes of A D R V and cloned by c D N A. R D R Vds R N A was successfully amplified by RT-PCR with primer D 9 of A D R V to obtain an 814 bp equivalent band of the P C R product of the 9th gene of A D R V The R N A template is referred to as R D R V, fragment 9) and clones thereof. Digoxigenin labeling was used to prepare c D N A probes for A D R V Nos. 4, 5, 9 and R D R V 9 genes. Nucleotide point hybridization, Northern hybridization for homology comparison. As a result, three genes of A D R V, 4, 5 and 9, and a cDNA clone of R D R V, 9, were obtained. A D R V, 4, 5, 9 and R D R V, The dot hybridization and Northern blot analysis of c D N A probe showed that the hybridization signal was positive at the corresponding point of R N A and the corresponding fragment of both viruses, and the negative control was negative.
