Subviral particles of modern strains of influenza A viruses, i.e. A/New Caledonia/20/99 (H1N1), A/Moscow/10/99 (H3N2), reassortant X-31 (subtype H3N2) and B/Sichuan/379/99, were obtained by using two preparations of bromeline ("Sigma Co., Catalogues' Nos. B2252 and B5144). A selective ability of bromeline B5144 was detected to the proteolytic splitting of hemagglutinin of influenza A and B viruses. An influence of enzyme B5144 produced on influenza B viruses brought about an appearance of subviral particles...
