Abstract

Henritzi et al. detect in domestic pig populations in Europe Influenza A viruses with extended variability and antigenically distinct from human vaccine strains. Several isolates are resistant to human MxA and transmit by aerosol in ferrets. Building blocks of pre-pandemic influenza A viruses may be circulating in European swine populations.
