Abstract

We describe a rapid method for subtyping Mycobacterium tuberculosis based on PCR amplification of segments located between two distinct DNA repetitive elements. This method, double-repetitive-element PCR, classified 46 clinical isolates as having 25 distinct patterns; the conventional restriction fragment length polymorphism analysis classified the same isolates as having 23 distinct patterns. The double-repetitive-element PCR is a rapid subtyping method that has a discriminating power similar to that of the restriction fragment length polymorphism method.

摘要

我们描述了一种基于对位于两个不同DNA重复元件之间的片段进行PCR扩增来对结核分枝杆菌进行亚型分型的快速方法。这种方法,即双重复元件PCR,将46株临床分离株分为25种不同模式;传统的限制性片段长度多态性分析将同样的分离株分为23种不同模式。双重复元件PCR是一种快速亚型分型方法,其鉴别能力与限制性片段长度多态性方法相似。
