Abstract

A total of 0.3 to 0.4 kb of the promoter region of the 16S rRNA genes from Mycobacterium tuberculosis, M. gordonae, M. xenopi, and M. leprae was PCR amplified, cloned, and sequenced. The observed number of substitutions, insertions, and deletions exceeded those found in previously used target sequences, including the entire 16S coding region. A simple and generally applicable restriction fragment length polymorphism method that can be used to distinguish between mycobacterial species is described.

摘要

对来自结核分枝杆菌、戈登分枝杆菌、偶发分枝杆菌和麻风分枝杆菌的16S rRNA基因启动子区域总共0.3至0.4 kb进行了PCR扩增、克隆和测序。观察到的替换、插入和缺失数量超过了先前使用的靶序列(包括整个16S编码区域)中的数量。本文描述了一种可用于区分分枝杆菌菌种的简单且普遍适用的限制性片段长度多态性方法。
