Immunochemical Evaluation of The Infectious Pancreatic Necrosis (IPN) Carrier State in Salmonids and Other Species
One of the most serious and pervasive diseases of cultured salmonids is infectious pancreatic necrosis (IPN) which is caused by an unusual virus of the same name (IPNV). The disease is especially prevalent on the West coast of the U.S. and the Canadian Maritime Provinces, but is also found in Asia, the British Isles and Europe. More than fifty species of fish and shellfish have been determined to harbor the virus (Dorson, 1983), although overt disease is not a necessary consequence of infection. When disease does occur, however, it is lethal to a large proportion of the affected population; this has been documented in many species including Atlantic salmon, Salmo salar; Pacific salmon, Oncorhyncus sp.; striped bass, Morone saxitilis; menhaden, Brevoortia tyrranus; rainbow trout, Salmo gairdneri; brook trout, Salvelinis fontinalis; and eels, Anguilla sp. Isolation of the virus from asymptomatic animals has been accomplished with at least twenty other aquatic animals, including freshwaster, estuarine, and marine vertebrates and invertebrates. Among the more intriguing species infected are shrimp, hard clam, American and European oyster, blue crab, minnows, milkfish and tilapia (Dorson,1983).
