| 摘 要： | 目的：介绍核糖体DNA（rDNA）的内转录间隔区（ITS）序列的结构特征和在寄生虫学研究应用中的最新研究进展。方法：检索有关文献进行综合分析。结果：rDNA ITS1和ITS2序列为寄生虫的鉴定提供了非常有价值的遗传标记。结论：核糖体DNA上的ITS域序列的进化速度较其它区域快，具有高变异性，可以从中获得大量的遗传信息，已成为在种和亚种水平上对寄生虫进行分类鉴定的有效手段。

| Abstract: | Objective:To introduce the recent progress on the structural features of Ribosomal DNA internal transcribed spacer sequence and application in parasitology.Methods:Relative literatures were summarized and analyzed.Results:Ribosomal DNA internal transcribed spacer 1and internal transcribed spacer 2 sequence provided very valuable genetic markers in identification of parasites.Conclusion:Ribosomal DNA internal transcribed spacer evolutionary faster than other regions.It had high variability and a lot of genetic information could be acquired.So Ribosomal DNA internal transcribed spacer has become a effective means in the classification identification in parasites species and subspecies. |
