Figure 2

Phylogenetic relationships of the N gene sequences from genotype D6 viruses from Brazilian, South American, and European sources. Tree shows representative genotype D6 sequences from Brazil, Argentina, Uruguay, and Bolivia, and viruses imported into the United States from Brazil (South American cluster) compared with genotype D6 sequences of viruses isolated in Europe or imported into the United States from European sources. Also shown are the sequences of the World Health Organization reference strains for each genotype.
