The infection status of domestic farmed eels Anguilla japonica, Anguilla bicolor and Anguilla marmorata with Japanese eel endothelial cell-infecting virus (JEECV) and anguillid herpesvirus 1 (AnHV) was examined at the major eel farming areas in Korea. These viruses were detected in all areas examined, regardless of the eel species or age. Any farm with a history of viral infection in adult fish confirmed the infection to be transmitted to stocked fry within 3 to 5 months. It is proposed that both viruses are horizontally transmitted within a given farm. The primary symptoms and histopathological lesions produced by the two viral infections are similar, making it difficult to distinguish the two diseases through clinical symptoms. Both viruses displayed 100% detection in the gills, suggesting that the gills are an optimal tissue for JEECV and AnHV monitoring. This study concluded that JEECV and AnHV were prevalent on eel farms across the country and caused very high mortality when the two viruses co-infected fry. Additional studies, including experimental infections, are needed to clearly understand the pathogenicity of each virus and the risk of co-infection.

양식 동남아산 뱀장어 Anguilla bicolor에 아가미의 출혈 및 간장의 충혈을 특징으로 하는 질병의 원인을 조사한 결과 Anguillid herpesvirus (AngHV-1) 의 감염이 확인되었다. 병어는 병리조직학적으로 아가미의 상피세포의 증생과 모세혈관의 출혈, 간장의 공포변성 및 중심정맥의 충혈이 관찰되었다. 병어를 $35^{\circ}C$에 10일간 승온 사육한 결과 아가미의 형태가 건강어의 아가미와 유사한 형태로 회복되었으며, 폐사율도 10%로 승온 처리가 폐사율 감소에 효과적인 것으로 나타났다.
