Abstract

Abstract: The hemagglutinins of H3 influenza viruses isolated from migratory ducks on the Pacific flyway in Japan during the period 1977 to 1985 were analyzed antigenically and genetically. Antigenic analysis using monoclonal antibodies to the hemagglutinins of A/Aichi/2/68 (H3N2) and A/duck/Hokkaido/8/80 (H3N8) viruses showed that antigenic drift occurred extensively in human strains, whereas the hemagglutinins of duck viruses were highly conserved. It was also found that the hemagglutinins of duck viruses were antigenically closely related to that of human 1968 H3 prototype strains. Nucleotide sequence analysis of seven duck H3 hemagglutinin genes showed a limited number of changes among the six duck isolates and between these duck isolates and Aichi/68. The deduced amino acid sequence revealed amino acid changes randomly distributed throughout the molecule and not confined to antigenic sites. These findings indicate that the duck virus hemagglutinin genes are conserved in nature and that viruses of different lineages cocirculate.
