Development of real-time reverse transcriptase PCR assays to detect and serotype dengue viruses.
Serotyping dengue virus (DENV) from suspect human specimens is crucial for developing sound epidemiological control measurements early in the transmission season and for effective patient management. We modified DENV consensus D1 (mD1) and serotype-specific TS2 (mTS2) and redesigned serotype-specific TS1 (rTS1) and TS4 (rTS4) as described previously in the conventional capsid and premembrane ge...
متن کاملRapid detection of classical swine fever virus by a portable real-time reverse transcriptase PCR assay.
A fluorogenic-probe hydrolysis (TaqMan)-reverse transcriptase PCR assay for classical swine fever virus (CSFV) was developed and evaluated in experimentally infected swine. The assay detected CSFV, representing different phylogenetic groupings, but did not amplify viral RNA from related pestiviruses. The assay met or exceeded the sensitivity (1 to 100 50% tissue culture infective doses per ml) ...
متن کاملDevelopment and Validation of a Quantitative, One-Step, Multiplex, Real-Time Reverse Transcriptase PCR Assay for Detection of Dengue and Chikungunya Viruses.
Dengue virus (DENV) and chikungunya virus (CHIKV) are important human pathogens with common transmission vectors and similar clinical presentations. Patient care may be impacted by the misdiagnosis of DENV and CHIKV in areas where both viruses cocirculate. In this study, we have developed and validated a one-step multiplex reverse transcriptase PCR (RT-PCR) to simultaneously detect, quantify, a...
متن کاملReal-time reverse transcriptase PCR assay for detection of human metapneumoviruses from all known genetic lineages.
The discovery of human metapneumovirus and its implications for respiratory tract disease have emphasized the need for a sensitive, specific, and rapid assay to detect this virus in a clinical setting. It recently became clear that human metapneumovirus can be grouped into at least four genetic lineages. Previously described assays for the detection of human metapneumovirus were developed by us...
متن کاملPCR - Based Reverse Transcriptase Assay
ES cells. This phenomenon has been observed in our laboratory in a number of cases. Clones putatively identified as homologous recombinants by Southern analysis can be quickly checked for random insertion of extra copies of the targeting vector by PCR. Given the small difference in size between the two alleles and use of only two primers common to both WT and mutant DNA, the amplification rate ...
