Data on isolation of chicken influenza virus strains in this country during epizootics in 1970--1975 are presented, and the antigenic characteristics of the isolates are described. All the strains had a mixed hemagglutinin type (GP6-H3N2) and neuraminidase H2. Neuraminidase of the strains had more marked antigenic relationship with H2 human influenza A/Singapore/57 (H2N2) virus than H2 of other human influenza virus strains. The size of KM of neuraminidase is similar in all chicken influenza virus strains their antigenic formula is suggested [A(GP6-H3N2)].
