| Research Abstract |
Viral disease is a serious problems of fish in hatchery. Especially, viral nervous necrosis of marine fish and infectious hematopoietic necrosis of salmonids are difficult to control. In this study, we studied and established the highly sensitive and specific diagnostic method to detect the virus specific gene using polymerase chain reaction (PCR) method. Results obtained in this study are summarized as follow.
1. Striped jack nervous necrosis virus (SJNNV) coat protein gene and infectious hematopoietic necrosis virus (IHNV) N protein gene were amplified by polymerase chain reaction (PCR) an could apply for the specific and sensitive diagnosis of VNN and IHN.
2. Rainbow trout embryo (RTE-2) and sea bass kidney (SBK-2) cell lines were selected for the isolation of IHNV and NNV.
3. Method of the simultaneous detection and identification of both IHNV and infectious pancreatic necrosis virus (IPNV) in a single PCR reaction was developed.
4. Fish nodaviruses were clasified into 4 clusters by molecular phylo-genetic analysis of the coat protein gene.
5. Combination of RT-PCR and antibody screening by ELISA was effective method for the identification of nervous necrosis viurs carriers in a flounder brood stock.
