From: Identification and isolation of Genotype-I Japanese Encephalitis virus from encephalitis patients
Phylogenetic analysis of JEV strains in CSF from JE patients, China. (A) Phylogenetic analyses based on the PrM gene of JEV; (B) Phylogenetic analyses based on the E gene of JEV; (C) Phylogenetic analyses based on the full-length genome of JEV. Phylogenetic analyses were performed by the neighbor-joining method using MEGA version 4 http://www.megasoftware.net. Bootstrap probabilities of each node were calculated with 1,000 replicates. The tree was rooted by using Murray Valley encephalitis virus (MVEV) sequence as the out group virus. Horizontal branch lengths are proportional to genetic distance and vertical branch lengths have no significance. The scale indicates the number of nucleotide substitutions per site. Sequences from this study are in boldface. Viruses were identified by using the nomenclature of virus strain/GenBank number/country/year of isolation/origin as showed in Figure 1(A).
