초록
1998년 8~10월에 남해안 일원 해상 가두리 양식장에서 사육중인 돌돔, Oplegnathus fasciatus이 60%이상 폐사하였다. 병어의 체색은 검어지거나 퇴색되며 아가미는 빈혈증상이 심하고 비장은 특이적으로 비대되어 있었고, 비장, 신장, 심장 및 간장 조직에서 퓰겐양성과 호염기성의 비대세포가 관찰되었다. 병어의 비장조직 마쇄액을 GF세포에 접종배양한 결과, 세포가 구형화 되면서 커지는 세포변성효과가 나타나 감염된 GF 세포로부터 바이러스가 분리되었다. 분리된 바이러스 배양액(
From August to October 1998, over 60% mortality of cultured striped beakperch Oplegnathus fasciatus was occurred in net cages along the southern coast of Korea. Moribund fish showed some clinical signs of lethargic behavior, dark coloration or decoloration, severe gill anemia and enlargement of spleen. Also enlarged basophilic cells showing Feulgen -positive reaction were observed in the tissue section of spleen, kidney, liver and heart of the diseased fish. GF cells inoculated with spleen homogenate of diseased fish produced cytopathic effect of enlarged and rounded cells, therefore the causative virus was isolated from diseased fish. Striped beakperch fingerlings intraperitoneally inoculated with the causative virus (
