UNASSIGNED: In this study, we used a reverse transcription-recombinase polymerase amplification-lateral flow dipstick (RT-RPA-LFD) method for the dual detection of IAPV and CBPV. RPA primers and LFD detection probes were designed separately for their conserved genes. Primers and probes were screened, and the forward and reverse primer ratios, reaction times, and temperatures were optimized. According to the results of the optimization tests, the optimal reaction temperature for RT-RPA is 37°C, and when combined with LFD, detection with the naked eye requires <20 min. The developed RPA-LFD method specifically targets IAPV and CBPV and has no cross-reactivity with other common bee viruses. In addition, the minimum detection limit of the RT-RPA-LFD method is 101 copies/μL.
UNASSIGNED: Based this study, this method is suitable for the detection of clinical samples and can be used for field detection of IAPV and CBPV.
■在这项研究中,我们使用逆转录-重组酶聚合酶扩增-侧流试纸(RT-RPA-LFD)方法双重检测IAPV和CBPV.针对其保守基因分别设计了RPA引物和LFD检测探针。引物和探针进行筛选,以及正向和反向引物比率,反应时间,和温度进行了优化。根据优化试验的结果,RT-RPA的最佳反应温度为37°C,当与LFD结合时,用肉眼检测需要<20分钟。开发的RPA-LFD方法专门针对IAPV和CBPV,与其他常见的蜜蜂病毒没有交叉反应性。此外,RT-RPA-LFD方法的最低检测限为101拷贝/μL。
■基于这项研究,该方法适用于临床样品的检测,可用于IAPV和CBPV的现场检测。
