Genetically characterized swH3N2 and swH3N1 isolates from Europe. (a) Numbers of isolates sequenced in this study plotted against the year of isolation and itemized by clades. (b) Genotypes of complete swH3N2 and swH3N1 genomes sequenced by the Jena Swine Influenza Virus Sequencing Initiative (SIVSI) consortium or available from the GenBank and EpiFlu databases. Abbreviations: H3.seas, gene segments of the seasonal human H3N2; H3.hu1, H3.hu2, H3.hu3, HA sublineages of IAV-S derived from the human seasonal HAH3 gene; 2A.hu1a, 2A.hu1b, 2A.hu2, 2A.hu2b, NA sublineages derived from the human seasonal NAN2 gene (2A.seas); 2A.hu1a*, drift variant of the 2A.hu1a sublineage (derived from Diepholz/2008-like swH1N2); EA, gene segments derived from the European avian-like swH1N1; pdm, gene segments derived from A(H1N1)pdm09; abbreviations of countries: A Austria, BE Belgium, DK Denmark, FR France, GER Germany, HUN Hungary, IT Italy, NE the Netherlands, SP Spain, UK United Kingdom.
