|Abstract||This report describes the clinical and histopathological features of infectious salmon anaemia virus infection in salt water farmed Atlantic salmon in the Bay of Fundy, New Brunswick, in the late summer of 1997. The virus was isolated from several sites by culture on SHK-1 cells and confirmed by monoclonal indirect fluorescent antibody technique. Gross examination revealed branchial pallor, exophthalmos, external ventral petechial haemorrhage, ascites and congested pyloric caecae, lower intestines and spleens. Microscopic examination was characterized by renal interstitial haemorrhage and tubular necrosis, branchial lamellar and filamental congestion and congestion of the intestine and pyloric caecae. Perivascular inflammation was a common finding in the livers examined. The lesions in the kidney were consistent with haemorrhagic kidney syndrome and were reproduced experimentally. This appears to be the first case report of infectious salmon anaemia in New Brunswick..|
