Abstract
The complete genome of the Japanese encephalitis virus JEV strain JEV/eq/India/H225/2009H225 isolated from an infected horse in India was sequenced and compared to previously published JEV genomes H225 genome was 10977nucleotides long comprising a single ORF of 10299nucleotides a 5′UTR of 95 nucleotides and a 3′UTR of 582 nucleotides The H225 genome showed high levels of sequence identity with 47 fully sequenced JEV genomes ranging from 993 to 755 for nucleotides and 992 to 915 for amino acid sequences Phylogenetic analysis of the fulllength sequence indicated that the H225 strain belongs to genotype III and is closely related to the Indian JEV strain Vellore P20778 A comparison of amino acids associated with neurovirulence in the E proteins and nonstructural proteins of known virulent and attenuated JEV strains suggested H225 to be a highly virulent strain This is the first report of wholegenome sequencing of a genotype III JEV genome isolated from equines
