TABLE 2.
Gene | Subtype | Pairwise genetic distance |
---|---|---|
NA | H5N6 | 0.049 |
PB2 | H5N6 | 0.025 |
PB1 | H5N6 | 0.009 |
H9N2 | 0.016 | |
PA | H5N6 | 0.01 |
NP | H5N6 | 0.013 |
M | H5N6 | 0.006 |
NS | H5N6 | 0.021 |
The pairwise genetic distance was estimated by the average number of substitutions per site over all sequence pairs between H3N6 and H5N6/H9N2 viruses.
