title: [Quantitative indices and physico-chemical properties of non-specific inhibitors of influenza A virus hemagglutination in the sera of different species of animals and birds].
abstract: The results of studies of the quantitative values of nonspecific antihemagglutinins of influenza viruses in the sera of birds, laboratory, wild and domestic animals (altogether 27 species) are presented. The antiviral inhibitors characterized by a number of physicochemical properties (sensitivity to heating, KIO4, trypsin, rivanol, 2-mercaptoethanol) were divided into 3 groups, sera of sheep, goats and cattle making up a separate group with regard to their sensitivity to heating and treatment with KIO4. Studies using molecular screen chromatography demonstrated the nonspecific inhibitors present in bovine sera to be heterogenous both in type (thermolabile and thermostable) and in the molecular composition. Alongside with thermolabile inhibitors of macroglobulin nature, thermostabe 19S and 4S inhibitors were identified.
