Complete Genome Sequence of a Novel Reassortant Avian Influenza H1N2 Virus Isolated from a Domestic Sparrow in 2012

摘要

We report here the complete genome sequence of a novel H1N2 avian influenza virus strain, A/Sparrow /Guangxi/GXs-1/2012 (H1N2), isolated from a sparrow in the Guangxi Province of southern China in 2012. All of the 8 gene segments (hemagglutinin [HA], nucleoprotein [NP], matrix [M], polymerase basic 2 [PB2], neuraminidase [NA], polymerase acidic [PA], polymerase basic 1 [PB1], and nonstructural [NS] genes) of this natural recombinant virus are attributed to the Eurasian lineage, and phylogenetic analysis showed that those genes are derived from H1N2, H3N1, H3N2, H4N6, H6N2, H10N8, H5N1, and H4N6 avian influenza viruses (AIVs). The amino acid motif of the cleavage site of HA is PSIQSR↓GLF. The sequence analysis will help in understanding the molecular characteristics and epidemiology of the H1N2 influenza virus in sparrows.
