Single-tube, nested, reverse transcriptase PCR for detection of viable Mycobacterium tuberculosis.
Several problems remain before molecular biology-based techniques, such as PCR, are widely accepted for the detection of infectious agents. Among the most formidable of these problems are the inability of the tests to distinguish between viable and nonviable organisms. We approached this problem by using the fact that bacterial mRNA has an extremely short half-life, averaging only a few minutes...
متن کاملA sensitive and quantitative single-tube real-time reverse transcriptase-PCR for detection of enteroviral RNA.
BACKGROUND Enteroviruses (EVs) are significant human pathogens. Rapid and sensitive diagnostic techniques are desirable. OBJECTIVES To develop a quantitative single-tube real-time reverse transcription-polymerase chain reaction (RT-PCR) for human enterovirus ribonucleic acid (RNA) (QPCR), with protection against amplimer contamination. STUDY DESIGN The method was evaluated with serial dilut...
متن کاملSingle-tube nested PCR in the diagnosis of tuberculosis.
AIMS To evaluate the usefulness of a single-tube nested polymerase chain reaction (PCR) assay in the diagnosis of tuberculosis in 1497 pulmonary and 536 extrapulmonary specimens. METHODS A single-tube nested PCR, utilising two sets of primers with different melting temperatures (88 degrees C for external primers; 70 degrees C for internal primers) to augment sensitivity and specificity withou...
متن کاملSingle-tube nested PCR assay with in-house DNA extraction for Mycobacterium tuberculosis detection in blood and urine.
INTRODUCTION Molecular analyses are auxiliary tools for detecting Koch's bacilli in clinical specimens from patients with suspected tuberculosis (TB). However, there are still no efficient diagnostic tests that combine high sensitivity and specificity and yield rapid results in the detection of TB. This study evaluated single-tube nested polymerase chain reaction (STNPCR) as a molecular diagnos...
متن کاملDetection of Mycobacterium tuberculosis from sputum specimens using one-tube nested PCR.
One-tube nested PCR was developed for diagnosis of pulmonary tuberculosis using sequences based on thel6SrRNA gene. The usage of primers 16SOL, 16SOR, 16SIL and 16SIR with optimized conditions could detect 555 bp DNA band from 21 species, 41 strains of mycobacteria and one isolate of Nocardia asteroides. It also revealed a specific 306 bp DNA band from 59 strains of M. tuberculosis complex. Cro...
