Dengue virus replicative intermediate RNA detection by reverse transcription-PCR.

Dengue virus replication involves synthesis of a replicative intermediate RNA (RI-RNA), whose presence reveals an actual infection. We report on a simple and rapid reverse transcription-PCR for the detection of viral RI-RNA in infected cells. The product is demonstrated at 20 min postinfection. This method is useful for the study of virus-cell tropism.

A Reverse transcription-PCR assay for detection of type A influenza virus and differentiation of avian H7 subtype

Abstract : Avian influenza virus (AIV) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. Although the risk of infection with avian influenza virus (AIV) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the ra...

Rapid detection and differentiation of dengue virus serotypes by a real-time reverse transcription-loop-mediated isothermal amplification assay.

The development and validation of a one-step, real-time, and quantitative dengue virus serotype-specific reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay targeting the 3' noncoding region for the rapid detection and differentiation of dengue virus serotypes are reported. The RT-LAMP assay is very simple and rapid, wherein the amplification can be obtained in 30 min u...

Detection and differentiation of Schmallenberg, Akabane and Aino viruses by one-step multiplex reverse-transcriptase quantitative PCR assay

BACKGROUND Schmallenberg virus (SBV), Akabane virus (AKAV) and Aino virus (AINV) are members of the Simbu serogroup within the genus Orthobunyavirus, family Bunyaviridae, which can cause reproductive disorders including abortion, stillbirth and congenital malformation in ruminants. Because, the clinical signs are similar, confirmatory diagnosis requires viral detection to differentiate infectio...
