FIGURE 2.
Phylogenetic analysis of different genomic regions of the 25 new isolates and 122 reference strains. (A) Full-length E2 gene sequences. (B) Partial E2 gene sequences. 23 newly isolated strains (indicated by ) accompanied with seven references strains (indicated by
) were clustered into subgenotype 2.1d. The other two newly isolated strains (labeled by
) belonged to subgenotype 2.1b.
