摘要： Infectious bursal disease (IBD), a major disease of birds, is caused by infectious bursal disease virus (IBDV). The disease can lead to immunosuppression, resulting in huge economic losses in the poultry industry. A specific, rapid, and simple detection method is important for the early diagnosis and prevention and control of IBDV. In this study, we established a naked-eye visual IBDV detection method, named "RPA-Cas12aDS", by combining recombinase polymerase amplification (RPA) with CRISPR-Cas12a-based nucleic acid detection. The detection process can be accomplished in 50 min, and uncapping contamination can be avoided. The detection results can be observed under blue or UV light. We used the RPA-Cas12aDS method to detect IBDV in bursa of Fabricius tissue samples of chickens, and the results were consistent with those obtained using commercial RT-PCR kits. This method presents great potential for visual, rapid, and point-of-care molecular diagnostics of IBDV in poultry.
