title: [The interrelations of the human and avian influenza viruses A(H2) determined by the mathematical processing of data on the antigenic structure of their hemagglutinin].
abstract: Mathematical methods were used to analyse the data on the antigenic specificity of H2 subtype hemagglutinin of human and avian influenza A viruses. This approach allowed the evaluation of possible evolutional relationships in this little-studied group of viruses. Influenza A (H2) viruses isolated from birds in the USA were found to represent a sufficiently isolated group, whereas European avian strains (A/duck/Germany/1215/73, A/pintail duck/Primor'e/695/76, A/duck/Marseilles/46/76) were close to "human" viruses. The A/Leningrad/1468/65, A/laughing gull/New Jersey/75/85, and A/pintail duck/Alberta/2728/77 strains represent marked antigenic variants apparently rather far gone as a result of hemagglutinin drift.
