Results from whole genome sequencing of isolated viruses.

To explore the genetic evolution of H9N2 IAV in East China, this study conducted a collection of 436 samples and swabs from various breeding enterprises and farmers in the region between 2018 and 2019. Among these samples, 50 tested positive for the H9 subtype, leading to the purification of 31 virus strains via limited dilution within chicken embryos. The following file contains the whole genome sequencing results of the isolated viruses.
