Abstract
The complete genomes of two swine influenza viruses from England were sequenced. Phylogenetic analysis revealed classical swine H1N1 viruses, one of which, A/swine/London, is closely related to virus strains of the early 1930s. Both strains are also antigenically related to A/swine/Iowa/15/1930, the strain originally isolated by Richard Shope. The source of A/swine/London is unknown, but its relationship to early classical swine influenza viruses suggests that the emergence of these viruses in Europe has to be antedated by 15-20 years.
