BIOLOGIC AND ANTIGENIC CHARACTERISTICS OF INFLUENZA VIRUSES TYPE A ISOLATED IN THE TOWN OF VARNA DURING 1996-1998

V. Rusev

Abstract

The haemadsorption, haemagglutination, and inhibitor-susceptibility as well as the eluent, pathogenic, toxic, and immunogenic activity of 10 isolated influenza type A strains were examined using modern methods for studying their antigenic structure and some biological properties. The investigations showed a continuous active circulation of influenza virus type A with antigenic formula H3N2 similar to that of standard strains AJ Beijing/32/92, Johanesburg/33/95, and A/Uhan/359/95 with the corresponding biological properties.


Keywords
