16S～23S rDNA区间序列是继16S rRNA后又一分类及鉴别细菌的新方法,它集保守性和可变性于一身,不但可用以菌种间鉴别,还可用来分辨16S rRNA不能鉴别的非常接近的菌种和种内菌株之间鉴别。16S rRNA的区域2和23S rRNA的区域10是构建区间序列的最好引物,已广泛用于菌种及菌株的鉴别。
The 16S ~ 23S rDNA interval sequence is a new method for the further classification and identification of bacteria after 16S rRNA. It combines conservation and variability and can be used not only for identification of species but also for distinguishing 16S rRNA from being very close The identification of strains and strains within the species. Region 2 of 16S rRNA and region 10 of 23S rRNA are the best primers for constructing the interval sequence and have been widely used for the identification of strains and strains.
