Figure 7From: Complete genome sequencing and analysis of six enterovirus 71 strains with different clinical phenotypesPhylogenetic tree hylogenetic analysis based on 3′-UTR nucleotide sequences. ● strains without neurovirulence, ▲ strains with neurological symptom. The phylogenetic tree was drawn using the neighbor joining method. Bootstrap values are shown as percentages derived from 1000 samplings and the scale reflects the number of nucleotide substitution per site along the branches.Back to article page
