Abstract

During surveillance for avian influenza viruses (AIVs) in live-poultry markets (LPMs) in eastern China in 2013, one H5N2 AIV was isolated from a duck. Phylogenetic analysis showed that the hemagglutinin of this strain belongs to clade 2.3.4 and received its genes from H5, H3 and H6 AIVs of poultry in China. The virulence of this strain was examined in chickens and mice, and it was found to be highly pathogenic in chickens but demonstrated moderate pathogenicity in mice. These results suggest that active surveillance of AIVs in LPMs should be used in an early warning system for avian influenza outbreaks.
