Figure 1

Phylogenetic analysis of JEV strains, with the Murray Valley encephalitis virus strain MVE 1–51 (GenBank accession number NC-000943) as an outgroup. (a) Tree based on a 240-nucleotide sequence of the core-premembrane gene region. (b) Tree based on a 1500-nucleotide sequence of the envelope gene region. Vientiane isolates are indicated in the box, and Okinawan isolates are indicated as ^*. G1a subcluster and G1b subcluster of JEV genotype 1, indicated in the dot line box, according to Nitpattana and others (2008).
