中文摘要：

近些年围绕16S～23SrRNA基因间隔区发展起来的分子生物学技术为细菌多样性的研究开辟了新的途径,使得人们在细菌多样性的研究中得以摆脱传统分离培养的束缚,进而使分析方法得以长足拓展,并为指导实践提供可靠的理论依据,作者就16S～23SrRNA基因间隔区序列的特点、应用及发展前景作一简述。

英文摘要：

In recently years,molecular biology techniques,based on the intergenic spacer region between 16S rRNA and 23S rRNA,has developed some new approaches to study the bacterial diversity.This technique which doesn＇t depend on traditional ways expands related analysis methods and provides reliable theoretical basis.This study reviewed the sequence features,applications and development prospects of 16S to 23S rRNA intergenic spacer region.
