| 内容記述 | Hirame rhabdovirus (HRV, Rhabdovirus olivaceus) was recently discovered from moribund hirame (Paralichthys olivaceus) and has been found widely in the Japanese hirame culture farms and it also is thought to have pathogenicity to salmonid fish. To establish the prevention technique of the disease by HRV in salmonid fish, histopathological observations for the salmonids and hirame and examination of HRV pathogenicity in salmonids were made. Diseased fish showed hemorrhage in muscle, congestion of gonad and accumulation of ascitic fluid in hirame. Histopathological observation showed necrosis and hemorrage in kidney and spleen. Hyperemia and hemorrhage were observed in the tissue of somatic muscle, alimentary tract, testis and ovary. Pathogenicity of the HRV was shown in rainbow trout: Oncorhynchus mykiss and masu salmon : O.masou in salmonid fish (rainbow trout, masu salmon, chum salmon: O.keta, coho salmon; O.kisutch, and pink salmon: O. gorbuscha) by artificial infection. Club-like or cord-like structures were easily recognized on the cell surface of HRV infected rainbow trout gonad cells (RTG-2) by electromicroscopical observations. Most of them contained many viral particles on the surface. These morphological characters were of HRV. On the artificial infection of HRV to hirame, any symptoms of the disease was not observed at water temperature higher than 15℃ in the range examined between 5 and 20℃. This indicated that regulation of breeding water temperature was effective for prevention of HRV infection. The ultraviolet irradiation of 6.0~7.8×10³μW·sec/cm² and disinfectants (500ppm of saponated cresol, 200ppm of benzalkonium chloride, 100ppm of iodine and 50ppm of sodium hypochlorite) were effective to inactivate HRV. | |||||
