qPCR-High resolution melt analysis for drug susceptibility testing of Mycobacterium leprae directly from clinical specimens of leprosy patients
BACKGROUND Real-Time PCR-High Resolution Melting (qPCR-HRM) analysis has been recently described for rapid drug susceptibility testing (DST) of Mycobacterium leprae. The purpose of the current study was to further evaluate the validity, reliability, and accuracy of this assay for M. leprae DST in clinical specimens. METHODOLOGY/PRINCIPAL FINDINGS The specificity and sensitivity for determinin...
متن کاملA RAPID AND SIMPLE METHOD OF DNA EXTRACTION FROM CLINICAL SPECIMENS CONTAINING MYCOBACTERIUM LEPRAE FOR PCR ASSAYS
We describe a rapid, simple, and reliable procedure for routine isolation of Mycobacterium leprae DNA from slit-skin swab specimens. This one-step DNA extraction method is based on the utilization of ChelexR 100, a chelating ion exchange resin. Slit-skin swab specimens from seven untreated leprosy patients at Baba Baghi Leprosy Hospital in Iran were processed by this procedure. The polymer...
متن کاملReal-time PCR and high-resolution melt analysis for rapid detection of Mycobacterium leprae drug resistance mutations and strain types.
Drug resistance surveillance and strain typing of Mycobacterium leprae are necessary to investigate ongoing transmission of leprosy in regions of endemicity. To enable wider implementation of these molecular analyses, novel real-time PCR-high-resolution melt (RT-PCR-HRM) assays without allele-specific primers or probes and post-PCR sample handling were developed. For the detection of mutations ...
متن کاملEvaluation of qPCR-Based Assays for Leprosy Diagnosis Directly in Clinical Specimens
The increased reliability and efficiency of the quantitative polymerase chain reaction (qPCR) makes it a promising tool for performing large-scale screening for infectious disease among high-risk individuals. To date, no study has evaluated the specificity and sensitivity of different qPCR assays for leprosy diagnosis using a range of clinical samples that could bias molecular results such as d...
متن کاملHigh-resolution melt PCR analysis for genotyping of Ureaplasma parvum isolates directly from clinical samples.
Ureaplasma sp. infection in neonates and adults underlies a variety of disease pathologies. Of the two human Ureaplasma spp., Ureaplasma parvum is clinically the most common. We have developed a high-resolution melt (HRM) PCR assay for the differentiation of the four serovars of U. parvum in a single step. Currently U. parvum strains are separated into four serovars by sequencing the promoter a...
