title: [Antigenic determinants in the makeup of the hemagglutinins of influenza virus type A (H3N2) isolated in 1977--1978].
abstract: Antigenic composition of hemagglutinins (HA) of influenza A viruses isolated during the epidemic of 1977--1978 was studied. Three antigenic determinants of H3.1, H3.5 and H3.7, identical to the determinants of HA of the viruses isolated in 1975, were detected in HA of the viruses isolated in 1977--1978 by means o the HAI test with inhibitor-free and monoreceptor sera. A/South Australia/1/77 virus was an exception in this group of viruses, and its HA contained only two determinants, H3.5 and H3.7, common with the HA of the viruses circulating in 1975. Neither the HAI test nor the biological neutralization tests showed H3.1 in A/South Australia/1/77 virus.
