Abstract

Restriction fragment length polymorphism and hybridization of DNA extracted from Mycobacterium tuberculosis, nontuberculous mycobacteria, and nonmycobacterial species with a probe derived from IS6110 confirmed that IS6110 was specific to M. tuberculosis complex. In addition, DNA amplification with IS6110-specific primers yielded a 181-bp fragment only in DNA from M. tuberculosis complex isolates.

摘要

用源自IS6110的探针,对从结核分枝杆菌、非结核分枝杆菌和非分枝杆菌属物种中提取的DNA进行限制性片段长度多态性分析和杂交,证实IS6110对结核分枝杆菌复合群具有特异性。此外,用IS6110特异性引物进行DNA扩增,仅在结核分枝杆菌复合群分离株的DNA中产生一个181bp的片段。
