title: Rapid detection of Infectious bursal disease virus by reverse transcription loop-mediated isothermal amplification assay.
abstract: A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the rapid identification of Infectious bursal disease virus (IBDV). The RT-LAMP assay used a set of 4 primers to amplify the viral protein 2 gene of IBDV for the detection of IBDV, showing not only high efficiency but also analytic specificity. The data demonstrated that the RT-LAMP assay detected 30 different IBDV isolates, had no cross-reaction with 3 other avian viruses (Infectious bronchitis virus, Newcastle disease virus, and Avian influenza virus), and obtained a 95.45% sensitivity in 22 positive clinical samples in reference to virus isolation. Therefore, this rapid, specific, sensitive, and convenient RT-LAMP assay could be applicable to the identification of IBDV in less-equipped laboratories as well as in the field.
