ABSTRACT

A comparative immunological analysis of the composition of antigenic determinants (AGD) in hemagglutinins of human influenza A virus (HIAV) of the serosubtypes H1, H2, H3, and in hemagglutinins of animal influenza viruses (AIV) of the serosubtypes H1, H3-H6, H8-H11 with 25 polyclonal highly active sera was demonstrated. Using original monospecific mon AGD in HIAV and AIV hemagglutinins was demonstrated. Using original monospecific antibodies to individual AGD, those AGD contributing to similarity and differences between HIAV and AIV were determined. It was found that influenza A. virus strains isolated from man in the USSR in 1986 were identical in the antigenic structure of hemagglutinin with that isolated from a tern in 1973 (A/tern/Turkmenistan/18/73).
