Development of a Single-Tube, Cell Lysis-Based, Genus-Specific PCR Method for Rapid Identification of Mycobacteria: Optimization of Cell Lysis, PCR Primers and Conditions, and Restriction Pattern Analysis

Abstract excerpt

A single-tube PCR method was developed for efficient identification of nontuberculous mycobacteria (NTM) and their environmental isolates in about 3 h without conventional DNA isolation. The following three steps were optimized or developed: (i). a simple, 6-min direct cell lysis protocol as a PCR prestep for generation of DNA-template, (ii). an improved Mycobacterium-specific PCR amplification protocol with a...
