[A novel isothermal amplification assay improves the capability for the field rapid detection of parasitic diseases]

With the rapid development of molecular biology, the isothermal amplification technique has been used for the nucleic acid detection of parasites and other pathogens due to its high efficiency and rapid and simple procedures, and has become an important tool to promote the field detection and control of parasitic diseases. Recombinase-aided isothermal amplification assay (RAA), a novel isothermal amplification technique, which is simple and easy to perform, rapid for field detection, no need for high-end equipment, and rapid field detection, may amplify the target gene fragments within 5 to 20 min under an isothermal condition (usually 37 to 42 ℃) and achieve a real-time observation of the amplification results. RAA has been successfully employed for the nucleic acid detection of a wide range of parasites and other pathogens to date, and has shown a high sensitivity and specificity. Notably, such an assay is suitable for the large-scale field detection in non-lab environments, and is therefore considered to have a potential value of application in rapid field detections.
