Genome Sequence of a Reassortant H5N1 Avian Influenza Virus Isolated from Domestic Green-Winged Teal.

An avian influenza virus strain, A/domestic green-winged teal/Hunan/3450/2006(H5N1) (DGW-T3450), was isolated from domestic green-winged teals. Genome analysis demonstrated that DGW-T3450 is a novel reassortant strain. The hemagglutinin (HA) and neuraminidase (NA) genes of this strain originated from H5N1 viruses circulating in poultry, while its remaining genes are derived from multiple ancestors, including viruses like those that infect wild birds.
