Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene.
Glycoprotein (G) gene nucleotide sequences of four Korean isolates of infectious hematopoietic necrosis virus (IHNV) were analyzed to evaluate their genetic relatedness to worldwide isolates. All Korean isolates were closely related to Japanese isolates of genogroup JRt rather than to those of North American and European genogroups. It is believed that Korean IHNV has been most likely introduced from Japan to Korea by the movement of contaminated fish eggs. Among the Korean isolates, phylogenetically distinct virus types were obtained from sites north and south of a large mountain range, suggesting the possibility of more than one introduction of virus from Japan.
