Objective: This paper focuses on the multiple detection RT-PCR technology of H5, H7, AND H9 subtype avian influenza viruses and Newcastle disease virus, and points out the specific detection methods and detection procedures of avian influenza and Newcastle disease virus. Methods: The genes of Newcastle disease virus carrying out the HA gene sequence of H5, H7 and H9 subtype AIV in GenBank were used to establish a strategy for simultaneous detection of three subtypes of avian influenza virus and Newcastle disease virus. Results: The results showed that the program can detect and distinguish H5, H7 and H9 subtype avian influenza viruses and Newcastle disease virus at one time. Conclusion: Multiple RT-PCR detection method has high detection sensitivity and can detect and determine different subtypes of avian influenza virus and Newcastle disease virus quickly and accurately, therefore, it has a crucial role in the detection and control of avian influenza H5, H7 and H9 subtypes and Newcastle disease.
