Phylogenetic tree based on the full E gene of the representative JEV strains.
The tree was constructed using the neighbor-joining method in Mega software version 4.0. The scale at the bottom of the tree indicates the number of nucleotide substitutions per site. Horizontal branch lengths are proportional to the genetic distance, while vertical branch lengths have no significance. The numbers above each branch represent the percentage of 1000 bootstrap replicate support. The tree was rooted using an outgroup sequence of Murray Valley encephalitis virus (MVEV). Newly isolated JEV strains in Wuhan are labeled with black diamonds on the left and belong to genotype 1. The older strain belonging to genotype 3 is labeled with a black square.
