    Influenza viral infection of swine in the United States 1988–1989 (1991)

    Notes: Summary Swine are an animal reservoir for influenza viruses capable of causing disease in humans. A serological survey in 1988–1989 demonstrates that subtype H1 influenza viruses continue to circulate at high frequency among swine in the north-central U.S.A. (average 51% incidence). Subtype H3 viruses antigenically similar to current human H3 viruses are circulating at low frequency (average 1.1%), particularly in the southeast U.S.A.

    Electron microscopic evidence for the association of M 2 protein with the influenza virion (1991)

    Notes: Summary Immunogold electron microscopy revealed that site-specific antibodies elicited by a synthetic peptide representing the N-terminal sequence (residues 2–10) of influenza virus M 2 protein were capable of binding to the surface of virions. Antibody binding was observed with two human influenza virus strains but not with an avian virus strain which has amino acid substitutions in the appropriate sequence of M 2. These results provide direct evidence for the presence of M 2 in the influenza virion.

    Replication of avian influenza viruses in humans (1991)
    Springer
    Archives of virology 119 (1991), S. 37-42

    Notes: Summary Volunteers inoculated with avian influenza viruses belonging to subtypes currently circulating in humans (H1N1 and H3N2) were largely refractory to infection. However 11 out of 40 volunteers inoculated with the avian subtypes, H4N8, H6N1, and H10N7, shed virus and had mild clinical symptoms: they did not produce a detectable antibody response. This was presumably because virus multiplication was limited and insufficient to stimulate a detectable primary immune response. Avian influenza viruses comprise hemagglutinin (HA) subtypes 1–14 and it is possible that HA genes not so far seen in humans could enter the human influenza virus gene pool through reassortment between avian and circulating human viruses.

    Relation between drug resistance and antigenicity among norakin-resistant mutants of influenza A (fowl plague) virus (1992)

    Archives of virology 124 (1992), S. 147-155

    Notes: Summary Norakin-resistant (NR) mutants of fowl plague virus (A/FPV/Wey-bridge, H7N7) have 1 to 2 (in one instance 3) amino acid substitutions in different positions of the heavy (HA 1) and/or light (HA 2) subunits of the haemagglutinin (HA) molecule. Investigation of NR mutants using the haemagglutination inhibition test with monoclonal antibodies (MAb) to the HA of A/seal/Massachusetts/80 (H7N7) virus revealed that one of the mutants (NR 1) differs antigenically from the wild-type fowl plague virus: its haemagglutination was not inhibited by MAb 55/2 and 58/6. By contrast, MAb-resistant (escape) mutants, selected from the wild-type fowl plague virus under pressure from MAb 55/2 or 58/6, showed reduced drug sensitivity. These findings suggest a possibility of correlation between alteration of influenza virus antigenicity and change of its sensitivity to drugs whose target is the haemagglutinin. This potential effect should be taken into account when antiviral substances directed to surface influenza virus antigens are being developed for use as antiviral drugs.
