Figure 1. Phylogenetic trees of the HA and NA genes of the H10 subtype strains isolated in Shanghai, China.
The neighbor-joining tree was constructed using the Kimura 2-parameter model in MEGA software version 6 (http://www.megasoft ware net/). Bootstrap values were calculated for 1000 replicates, and the values less than 75% were not shown. Numbers indicate neighbor-joining bootstrap values. Virus characterized in this study were indicated by black circles.

The analysis methods were the same as Figure 1.
Figure 3. Phylogenetic trees of the HA and NA genes of the H12 subtype strains isolated in Shanghai, China.
The analysis methods were the same as Figure 1.
Figure 4. Comparison of the number of H10-H12 subtypes in China and the world. (a) The number of H10-H12 subtypes isolated annually in China and the world since 1975. (b) The number of H10-H12 subtypes isolated in China and the world to date.
