Five H5N2 avian influenza viruses (AIVs) were isolated in Xianghai National Nature Reserve, Jilin Province, China in October 2011. They were all identified as low pathogenic AIVs (LPAIVs) based on their deduced amino acid sequences at the cleavage site of HA protein. Phylogenetic analysis revealed that all gene segments clustered in the Eurasian lineage and that the nucleotide homology of the five isolates was greater for HA and NA genes than for the genes for internal proteins PB2, PB1, PA, M, NP and NS.
