SURVEY OF INFLUENZA VIRUSES IN FERAL BIRDS IN 1979 AND ISOLATION OF A STRAIN POSSESSING Hav6Nav5 FROM CLOACA OF AN EASTERN DUNLIN

In the course of a survey in 1979 of influenza virus in feral birds, including 255 water fowls of 19 species, 719 small migrating birds of 32 species and 126 sea birds of 6 species, an influenza virus was isolated from a cloacal swab of one of the 38 eastern dunlins (Calidris alpina sakhalina) examined. No influenza virus was isolated from the other birds. The isolate possessed Hav6 hemagglutinin and Nav5 neuraminidase and was designated as A/eastern dunlin/Hokkaido/101/79 (Hav6Nav5)
