title: [Humoral immune response to the influenza virus: the fractionation of sera from immune animals].
abstract: The studies demonstrated that antibody synthesis under conditions of the investigated fatal influenza infection differs in certain parameters from that in non-fatal infection. The mouse-pathogenic A/PR8/34 strain of influenza virus actively induced synthesis of antibodies detectable both by HI and NT. The less pathogenic A/Krasnodar/101/59 strain induced synthesis of antibodies detectable by NT sufficiently well but was a poor inducer of antibodies inhibiting virus hemagglutination of chick erythrocytes. Antibodies detectable by HI and NT appear to represent different molecules of immunoglobulins which differ in their immunochemical properties. These antibodies could be separated by means of affinity chromatography on an immunosorbent. The results of the above studies confirm that the protective and virus-neutralizing activity of an immune preparation in passive immunization is determined by the qualitative and quantitative composition of antibodies in a given preparation. The ratio of virus-induced antibodies may possibly determine the severity of the course and outcome of primary influenza infection.
