[Abstract]:[objective] to establish a molecular biological method for rapid, simple and visual detection of bovine epidemic fever virus. [methods] two pairs of primers were designed according to 6 conserved regions of bovine prevalent fever virus G protein gene. In order to optimize the reaction conditions of RT-LAMP, a visualized reverse transcription loop-mediated isothermal amplification (RT-LAMPMPP) technique was established for the detection of bovine epidemic fever virus (BVV) by reverse transcription loop-mediated isothermal amplification. [results] when the concentration of Mg2 was 3 mmol / L ~ (-1), the concentration of betaine was 0.4 mol / L ~ (-1), the concentration of mix was 1.2 渭 mol / L ~ (-1), the ratio of internal and external primer was 8: 1 and the reaction temperature was 63 鈩，
