ABSTRACT: Since 2015, an outbreak of an infectious disease in broilers caused by fowl adenovirus serotype 4 (FAdV-4) has occurred in China, resulting in substantial economic losses. Rapid, accurate, and specific detection are significant in the prevention and control of FAdV-4. In this study, an FAdV-4 detection method combining loop-mediated isothermal amplification (LAMP) and Pyrococcus furiosus Argonaute (PfAgo) was established. Specific primers, guide DNAs (gDNAs), and molecular beacons were designed to target a conserved region of the FAdV-4 hexon gene. After optimizing the reaction conditions, the minimum detection of this assay could reach 5 copies. It only amplified FAdV-4, and there was no cross-reactivity with other pathogens. The assay took about only 50 min, and the results could be visualized with the naked eye under ultraviolet or blue light, getting rid of specialized instruments. This novel LAMP-PfAgo assay was validated by using 20 clinical samples and the results were identical to gold-standard real-time polymerase chain reaction method. In summary, the LAMP-PfAgo assay established in the paper provides a rapid, reliable, convenient, ultra-sensitive and highly specific tool for the on-site detection and clinical diagnosis of FAdV-4.
