Phylogenetic analysis of HA1 nucleotide sequences from South America, 2012. Maximum likelihood tree based on EIV strains isolated between 1963 and 2012. Bootstrap values obtained after 100 replicates are shown at major nodes. Major lineages and sub-lineages are labeled by bars on the right. The OIE recommended strains South Africa/4/03, Ohio/03 (Florida clade 1) and Richmond/1/07 (Florida clade 2) are in black uppercase letters. The vaccine strain Kentucky/97 is shown in green, the Brazilian strain Rio Grande do Sul/1/12 in blue, Dubai/1/12 and Argentina/E-2345-1/12 in red
