Abstract
Abstract: The evolution of the hemagglutinin (HA) of equine H3 influenza viruses was studied by analysis of nucleotide and deduced amino acid sequences, as well as reactivity of the HA molecule to ferret antisera and monoclonal antibodies. The evolutionary tree constructed from the nucleotide sequences clearly illustrated that the HA of equine H3 influenza viruses evolved in a single lineage, as has been shown for human influenza A viruses. Comparison of the nucleotide sequences of the HA genes of human, swine, avian, and equine viruses showed that the equine strains have evolved independently, without recent introduction of HA genes from other species. By contrast, the results of antigenic analysis indicated that equine H3 influenza viruses include multiple, cocirculating strains. This discrepancy suggests that antigenic analysis of viral proteins should be used with caution in studies of evolutionary pathways.
