초록
The outbreak of haemorrhagic speticemia and dermal lesions in cultured Rock sea breem in Jeju Island are frequently associated with keratitis. Prolonged infection leads to the symptoms accompanied by necrosis of fin and skin and the fishes died. Present study aims to study the histopathological changes of diseased fish muscle tissue. The tissue at the initial stage of infection showed normal muscular texture, however in the late stages of infection, muscular lesion had been expanded and hence, necrosis had progressed deeply into muscle tissue. Mild tissue in caudal fin was found with more necrosis, and gill tissues were also collapsed. In Kidney, renal tubules were teared along with tissue destruction (Espada, J et al, 1993). Hence in the present study, we examined the histopathological variation of the infection fishes, and this basic data would be used for future research of in haemorrhagic specticemia and dermal diseases.
Abstract
The outbreak of haemorrhagic speticemia and dermal lesions in cultured Rock sea breem in Jeju Island are frequently associated with keratitis. Prolonged infection leads to the symptoms accompanied by necrosis of fin and skin and the fishes died. Present study aims to study the histopathological changes of diseased fish muscle tissue. The tissue at the initial stage of infection showed normal muscular texture, however in the late stages of infection, muscular lesion had been expanded and hence, necrosis had progressed deeply into muscle tissue. Mild tissue in caudal fin was found with more necrosis, and gill tissues were also collapsed. In Kidney, renal tubules were teared along with tissue destruction (Espada, J et al, 1993). Hence in the present study, we examined the histopathological variation of the infection fishes, and this basic data would be used for future research of in haemorrhagic specticemia and dermal diseases.
