Abstract. A marine Vibrio sp. was isolated from Atlantic salmon suffering from Hitra Disease. This Vibrio sp. could be transmitted to Atlantic salmon through the water and from previously infected fish. The bacteria enter the fish through gills, although wounds appear to enhance the infectivity. Infected Atlantic salmon developed a condition similar to Hitra Disease, from which bacteria could be easily reisolated from dead and moribund fish.
