During the surveillance for avian influenza viruses (AIVs) in live poultry markets in Eastern China, in 2014, seven H6N2 AIVs were isolated from poultry. Phylogenetic analysis showed that these strains received their genes from H6, H3, and H9 AIVs of poultry in China. These strains were found to demonstrate moderate pathogenicity in mice, and were able to replicate in mice without prior adaptation. Considering that novel reassorted H6N2 viruses were isolated from poultry in this study, it is possible that these chickens and ducks play an important role in the generation of novel reassorted H6N2 AIVs.
