Outline of Final Research Achievements

The purpose of this study was to reveal the mechanism of neuropathogenicity of equine herpesvirus type 1 (EHV-1) at the molecular level. Comparing EHV-1 genomes of neuropathogenic and nonneuropathogenic strains, several open reading frames and amino acid substitution including ORF30 D752 neuropathogenic marker were identified. Particularly comparison of neuropathogenic strains possessing ORF30 N752 instead of D752 indicated several viral genes associated with neuropathogenicity of EHV-1. Transcription start site analyses on EHV-1 infected cells showed transcription from whole genome sequence at 8 hour post infection. These results indicated that virus transcription might be much complicated.
