a

Partial sequences of each gene of our isolates, together with sequences from GenBank, were analyzed by the distance-based neighbor-joining method using phylogenetic analysis software (MEGA 3.1). Nucleotide sequences of HA (positions 98 to 1059), NA (positions 746 to 1386), PB2 (positions 1037 to 2219), PB1 (positions 950 to 2177), PA (positions 1434 to 1580), NP (positions 747 to 1504), M (positions 149 to 888), and NS (positions 27 to 864) genes were examined in this study. GenBank accession numbers in boldface indicate that the gene segments are of avian origin; underlined accession numbers denote that the gene segments are of swine origin; the rest of the genes are of human origin.

b

The origin of these genes was reported previously (29).

c

Sequence analysis indicates that this gene is equally closely related to the HA gene of human and duck H3 viruses and may come from either origin.

d

A dash indicates that the sequence was not available from GenBank.
