Abstract:
From June to October in 1993~1995, cultured Penaeus chinesis and Penaeus japonicus occurred mass mortality at the farm in Western Sea of Korea. The disease was reproduced in healthy shrimp by injection of filtered (at 0.45 micromeger) homogenate of infected shrimp. So we concluded hat it was filterable agents like virus. Clinical symptoms were white spots on the carapace and reddish tail. Histopathological changes were characterized by hypertrophied nuclei at cuticular epidermis lymphoid organ, hematopoietic tissue. In negatively stained preparation, the virion revealed rod-shaped, enveloped, nonoccluded. Cytopathic effect (CPE) were not observed by virus in CHSE-214, RTG-2, EPC, FHM cell lines. Base on the above facts, the reason of mass mortality of penaied shrimp was baculovirus.
