Utility of rpoB gene sequencing for identification of nontuberculous mycobacteria

The Comparison of Biochemical and Sequencing 16S rDNA Gene Methods to Identify Nontuberculous Mycobacteria

The identification of Mycobacteria in the species level has great medical importance. Biochemical tests are laborious and time-consuming, so new techniques could be used to identify the species. This research aimed to the comparison of biochemical and sequencing 16S rDNA gene methods to identify nontuberculous Mycobacteria in patients suspected to tuberculosis in Golestan province which is the ...

Utility of rpoB Gene Sequencing for Identification of Nontuberculous Mycobacteria in the Netherlands

Utility of rpoB gene sequencing for identification of nontuberculous mycobacteria in the Netherlands.

In the Netherlands, clinical isolation of nontuberculous mycobacteria (NTM) has increased over the past decade. Proper identification of isolates is important, as NTM species differ strongly in clinical relevance. Most of the currently applied identification methods cannot distinguish between all different Mycobacterium species and complexes within species. rpoB gene sequencing exhibits a promi...

Simultaneous genotyping and species identification using hybridization pattern recognition analysis of generic Mycobacterium DNA arrays.

High-density oligonucleotide arrays can be used to rapidly examine large amounts of DNA sequence in a high throughput manner. An array designed to determine the specific nucleotide sequence of 705 bp of the rpoB gene of Mycobacterium tuberculosis accurately detected rifampin resistance associated with mutations of 44 clinical isolates of M. tuberculosis. The nucleotide sequence diversity in 121...

Detection of rifampin-resistant Mycobacterium tuberculosis in sputa by nested PCR-linked single-strand conformation polymorphism and DNA sequencing.

Either PCR-mediated single strand conformation polymorphism (SSCP) analysis or DNA sequencing of rpoB DNA (157 bp) can be used as a rapid screening method for the detection of mutations related to the rifampin resistance of Mycobacterium tuberculosis. However, due to the nonspecific amplification of rpoB DNA from nontuberculous mycobacteria these methods cannot be directly applied to clinical s...
