The application discloses a kind of pig multiple
diarrhea virus detection method and application based on tNGS technology.The method realizes the accurate detection of pig
epidemic diarrhea virus,
porcine transmissible gastroenteritis virus and porcine
delta coronavirus by tNGS technology.The primer set involved is used to amplify the S1 and M genes of PEDV, the N
gene of TGEV and the M
gene of PDCoV.The application also provides a kit comprising the primer set and a corresponding tNGS detection method.Clinical sample
verification shows that the method is completely consistent with the qPCR detection results, has high sensitivity, strong specificity, can simultaneously identify
mixed infection and other advantages, and has high detection
throughput, controllable cost, is suitable for accurate diagnosis,
epidemiological monitoring and prevention and control of
diarrhea virus in pig farm, and has wide application prospect.
