Infectious pancreatic necrosis (IPN) is a severe viral disease of salmonid fish. It is caused by infectious pancreatic necrosis virus , which is a member of the Birnaviridae family. This disease mainly affects young salmonids such as trout or salmon of less than six months, although adult fish may carry the virus without showing symptoms. [ 1 ]
Infectious pancreatic necrosis disease virus (IPNV) causes infectious pancreatic necrosis disease (IPN) in fish – most disease has been documented in young, farmed salmonid fish. [ 9 ] Infectious pancreatic necrosis disease virus (IPNV) is a bi-segmented, double-stranded RNA virus belonging to the Aquabirnavirus subgroup of the Birnaviridae ...
The virus was first described in 1976 in Scotland and in 1989 in Norway. It affects farmed Atlantic salmon (Salmo salar) caused by Marine SAV2 and SAV3 and has also been identified in Rainbow trout (Oncorhyncus mykiss) in the seawater phase caused by SAV2 where the disease is commonly referred to as Sleeping Disease (SD).

The bacterium is pathogenic for fish, and causes the disease known as furunculosis. [13] The symptoms the fish show are external and internal hemorrhaging, swelling of the vents and kidneys, boils, ulcers, liquefaction, and gastroenteritis. Furunculosis is commonly known as tail rot in fish and is common in goldfish and koi. Infected fish with ...
Computed tomography (CT) findings in AIP include a diffusely enlarged hypodense pancreas or a focal mass that may be mistaken for a pancreatic malignancy. [8] A low-density, capsule-like rim on CT (possibly corresponding to an inflammatory process involving peripancreatic tissues) is thought to be an additional characteristic feature (thus the ...
A pancreatic cyst is a fluid filled sac within the pancreas. The prevalence of pancreatic cysts is 2-15% based on imaging studies, but the prevalence may be as high as 50% based on autopsy series. [1] Most pancreatic cysts are benign and the risk of malignancy (pancreatic cancer) is 0.5-1.5%.
Protein is an essential macronutrient for everyone, and if you’re taking a weight loss drug, such as GLP-1 medications, you should be extra mindful about your intake.This is because muscle loss ...
This toxin results in the fish developing bleeding lesions, and their skin flakes off in the water. The dinoflagellates then eat the blood and flakes of tissue while the affected fish die. [33] Fish kills by this dinoflagellate are common, and they may also have been responsible for kills in the past which were thought to have had other causes ...
