Experimental infection of Atlantic salmon, Salmo salar L., with infectious salmon anaemia virus: a histopathological study.

摘要

Experimental infection of Atlantic salmon with a Canadian isolate of infectious salmon anaemia virus (ISAV) showed that pathognomonic hepatic ISA lesions were present in 90.6% and pathognomonic renal haemorrhagic kidney syndrome (HKS) lesions in 78.1% of fish which died after the experimental challenge. Both pathognomonic hepatic infectious salmon anaemia (ISA) lesions and pathognomonic renal HKS lesions were found together in 65.6% of fish which died after ISAV challenge. It is concluded that ISAVcan cause a very high prevalence of both HKS and ISA pathognomonic lesions.
