During surveillance for avian influenza viruses (AIVs) in live-poultry markets in Eastern China in 2013, an H11N9 AIV was isolated from a domestic duck. Phylogenetic analysis showed that this strain received its genes from H11, H3, H10, and H7 AIVs of poultry in China. This strain was found to be minimally pathogenic in mice and was able to replicate in mice without prior adaptation. Considering that the reassorted H11N9 viruses were isolated from domestic ducks in this study, it is possible that these ducks play an important role in the generation of novel reassorted H11 AIVs.
