title: Isolation, purification and characterization of polypeptides of influenza and parainfluenza viruses. Note III. Polypeptides of three influenza virus strains isolated in Romania.
abstract: An analysis is presented of the nature, number and relative molecular mass of the polypeptides of three influenza virus strains-A/Romania 1/73 (H3N2), A/Romania 1/75 (H3N2), and B/Romania 34/74-isolated during different epidemic outbreaks. The results obtained indicate some similarities between the protein subunits of the two influenza A virus strains (as concerns virus surface and nucleocapsid components) and point out the particular properties of the influenza B strain.
