Novel Technique of Quantitative Nested Real-Time PCR Assay for Mycobacterium tuberculosis DNA

Novel technique of quantitative nested real-time PCR assay for Mycobacterium tuberculosis DNA.

The diagnosis of tuberculous meningitis (TBM) remains a complex issue because the most widely used conventional diagnostic tools, such as culture and PCR assay for cerebrospinal fluid (CSF) samples, are unable to rapidly detect Mycobacterium tuberculosis with sufficient sensitivity in the acute phase of TBM. Based on TaqMan PCR, we designed a novel technique consisting of an internally controll...

Novel wide-range quantitative nested real-time PCR assay for Mycobacterium tuberculosis DNA: development and methodology.

Previously, we designed an internally controlled quantitative nested real-time (QNRT) PCR assay for Mycobacterium tuberculosis DNA in order to rapidly diagnose tuberculous meningitis. This technique combined the high sensitivity of nested PCR with the accurate quantification of real-time PCR. In this study, we attempted to improve the original QNRT-PCR assay and newly developed the wide-range Q...

NASBA Isothermal Technique: a Novel Tool for Mycobacterium tuberculosis Diagnosis

Background and Objectives: rapid, accurate and cost effective diagnosis of infectious and non infectious diseases is an essential step for treatment process. Nowadays, in Line with scientific progression in molecular biology, genetics and biochemistry which are based on biotechnology and genetic engineering aspects, new branch of medicine entitled molecular medicine is being derived. It can be ...

Detection of mycobacteria, Mycobacterium avium subspecies, and Mycobacterium tuberculosis complex by a novel tetraplex real-time PCR assay.

Mycobacterium tuberculosis complex, Mycobacterium avium, and many other nontuberculous mycobacteria are worldwide distributed microorganisms of major medical and veterinary importance. Considering the growing epidemiologic significance of wildlife-livestock-human interrelation, developing rapid detection tools of high specificity and sensitivity is vital to assess their presence and accelerate ...
