Development of New Real-time PCR Assays for Detecting <i>Megalocytivirus</i> Across Multiple Genotypes

Real-time multiplex PCR assays.

The ability to multiplex PCR by probe color and melting temperature (T(m)) greatly expands the power of real-time analysis. Simple hybridization probes with only a single fluorescent dye can be used for quantification and allele typing. Different probes are labeled with dyes that have unique emission spectra. Spectral data are collected with discrete optics or dispersed onto an array for detect...

Title : Development of Real - time , multiplex PCR / RT - PCR assays for improved

Porcine respiratory disease complex (PRDC) continues to be a significant economic problem for swine producers. Porcine reproductive and respiratory syndrome virus (PRRSV), Swine influenza virus (SIV), Porcine circovirus-2 (PCV-2), Mycoplasma hyopneumoniae, Actinobacillus pleuropneumoniae, and Pasturella multocida are among the most important pathogens contributing to PRDC. Recently, a new gener...

Comparative evaluation of conventional and real-time PCR assays for detecting Bacteroides fragilis in clinical samples.

A conventional PCR and a real-time PCR for detecting Bacteroides fragilis were evaluated against clinical specimens. Analytical sensitivities were 100 and 40 fg of DNA, respectively. Detection limits were 100 and 10 CFU/ml, respectively. A total of six culture-negative specimens were positive by PCR. Altering the gold standard from "positive culture" to "positive culture or both PCR assays posi...

Development of multiplex real-time reverse transcriptase PCR assays for detecting eight medically important flaviviruses in mosquitoes.

A multiplex real-time reverse transcriptase PCR has been developed for the rapid detection and identification of eight medically important flaviviruses from laboratory-reared, virus-infected mosquito pools. The method used involves the gene-specific amplification of yellow fever virus (YFV), Japanese encephalitis virus (JEV), West Nile virus (WNV), St. Louis encephalitis virus (SLEV), and dengu...
