Résumé
Capripoxvirus (CaPV) contains three viruses that have caused massive losses in the livestock and dairy industries. Accurate CaPV differentiation has far-reaching implications for effectively controlling outbreaks. However, it has a great challenge to distinguishing three viruses due to high homology of 97%. Here, we established a sensitive CRISPR/Cas12a array based on Multiple-recombinase polymerase amplification (M-RPA) for CaPV differentiation, which provided a more comprehensive and accurate differentiation mode targeting VARV B22R and RPO30 genes. By sensitive CRISPR/Cas12a and M-RPA, the actual detection limits of three viruses were as low as 50, 40 and 60 copies, respectively. Moreover, Lateral flow dipstick (LFD) array based on CRISPR/Cas12a achieved portable and intuitive detection, making it suitable for point-of-care testing. Therefore, CRISPR/Cas12a array and LFD array paved the way for CaPV differentiation in practice. Additionally, we constructed a real-time quantitative PCR (qPCR) array to fill the qPCR technical gap in differentiation and to facilitate the quarantine departments.
