A hemagglutinating agent was isolated from a tufted duck captured in Lake Shinji, Shimane Prefecture, Japan, and identified as influenza A by double immunodiffusion tests with the antiserum to influenza A virus ribonucleoprotein. The hemagglutinin of the isolate was antigenically related to that of A/New Jersey/8/76 but was not identical with it. The neuraminidase antigen of this Hswl subtype was closely related to that of A/turkey/Ontario/6118/68 and was shown to be Nav4 subtype. After experimental infection of 5‐week‐old SPF‐chickens with the isolate, virus was recovered from various organs including the brain, despite the absence of signs of disease. © owned by Center for Academic Publications Japan (Publisher)
