Infectious hematopoietic necrosis virus (IHNV) is a rhabdoviral pathogen that infects wild and cultured salmonid fish throughout the Pacific Northwest of North America. IHNV causes severe epidemics in young can cause disease or occur asymptomatically adults. In broad survey 323 field isolates, sequence analysis 303 nucleotide variable region within glycoprotein gene revealed maximum diversity 8.6 %, indicating low genetic overall for this virus. Phylogenetic three major genogroups, designated U, M L, which varied topography geographical range. Intragenogroup measures indicated genogroup had three- to fourfold more than other genogroups suggested relatively rapid evolution stasis U genogroup. We speculate factors influencing may have included ocean migration ranges their host populations anthropogenic effects associated with culture.
