摘要

分子技术提供了一种更快、更灵敏的方法,可直接从样本中检测结核分枝杆菌(Mtb)DNA,从而彻底改变了结核病(TB)诊断方法。单管嵌套 PCR (STNPCR) 将两个 PCR 反应与不同的寡核苷酸组合在一个试管中。此外,还研究了用于病原体检测的 PCR 产物比色法。因此,本研究旨在建立一种基于比色 STNPCR 的新型系统,使用微孔板和 IS6110 扩增片段检测 Mtb。结果显示,比色 STNPCR 的一般检测限为 1 pg/μl。其一般灵敏度和特异性分别为 76.62% 和 60.53%,卡帕指数一致度为 0.166。

Development and evaluation of a single-tube nested PCR with colorimetric assay for Mycobacterium tuberculosis detection.
Molecular techniques have revolutionized tuberculosis (TB) diagnosis by offering a faster and more sensitive approach, detecting Mycobacterium tuberculosis (Mtb) DNA directly from samples. Single-tube nested PCR (STNPCR) combines two PCR reactions with separate oligonucleotide sets in a single tube. Moreover, colorimetric methods in PCR products have been studied for pathogen detection. Thus, this study aimed to establish a novel system based on colorimetric STNPCR for Mtb detection using microtiter plates with IS6110-amplified fragments. The results showed a general colorimetric STNPCR detection limit of 1 pg/μl. Its general sensitivity and specificity were 76.62 and 60.53%, respectively, with kappa index agreement of 0.166.

期刊介绍: BioTechniques is a peer-reviewed, open-access journal dedicated to publishing original laboratory methods, related technical and software tools, and methods-oriented review articles that are of broad interest to professional life scientists, as well as to scientists from other disciplines (e.g., chemistry, physics, computer science, plant and agricultural science and climate science) interested in life science applications for their technologies. Since 1983, BioTechniques has been a leading peer-reviewed journal for methods-related research. The journal considers: Reports describing innovative new methods, platforms and software, substantive modifications to existing methods, or innovative applications of existing methods, techniques & tools to new models or scientific questions Descriptions of technical tools that facilitate the design or performance of experiments or data analysis, such as software and simple laboratory devices Surveys of technical approaches related to broad fields of research Reviews discussing advancements in techniques and methods related to broad fields of research Letters to the Editor and Expert Opinions highlighting interesting observations or cautionary tales concerning experimental design, methodology or analysis.
