ABSTRACT
Comparative studies of the biological properties, antigenic structure and ultrastructure of influenza A viruses isolated in the USSR, A/New Jersey/8/76 and A/swine/31 were carried out. Antigenic differences between A/USSR/02/76 and A/swine/31 strains as well as A/New Jersey/8/76 strain were found in the hemagglutination-inhibition and neuraminidase activity-inhibition tests. These differences were confirmed by serological examination of human sera.
