We evaluated the pathogenicity of Korean and Japanese isolates of viral hemorrhagic septicemia virus (VHSV: genotype IVa) from olive flounder Paralichthys olivaceus using rainbow trout Oncorhynchus mykiss fry. The cumulative mortalities of fish challenged with FYeosu05 (Korean) and Obama25 (Japanese) isolates at 106.5 TCID50/fish were 64 and 48%, respectively. No mortality was observed among the fish challenged with either of the isolates at 105.5 TCID50/fish, or in mock-challenged fish. The affected fish exhibited darkening of the body, an expanded abdomen, pale gills, an enlarged spleen, and diffuse necrosis in the splenic and interstitial hematopoietic tissues. We re-isolated VHSV from all mortalities using cell culture and confirmed their presence by reverse transcription loop-mediated isothermal amplification (RT-LAMP). We thus concluded that Asian VHSV isolates from olive flounder are pathogenic to rainbow trout fry, although with low virulence.
