Abstract
Duck circovirus disease (DuCVD) caused by duck circovirus (DuCV) continues to spread in recent years, which brings serious harm to the poultry industry, so early diagnosis of DuCVD is of great significance for the prevention and control of this disease. Specific primers and probes for DuCV were designed in this study. Reverse primers and probes were modified at the 5′ ends with biotin and fluorescein, respectively, and they were combined with dipsticks labeled with biotin antibodies and fluorescein antibodies to establish a recombinase-aided amplification-lateral flow dipstick (RAA-LFD) assay for detection of duck circovirus. By using this method, the reaction products reached detectable levels in about 20 min as a result of rapid amplification at a constant temperature of 37℃. The detection results could be observed by dripping the reaction products onto the dipstick within 2 to 3 min. The RAA-LFD method has good specificity and high sensitivity (102 copies/μL). Compared with conventional polymerase chain reaction (PCR), RAA-LFD has no power limit on the testing instrument, and is easy to use, saving more time and manpower, so it is more suitable for clinical detection.
