Figure 3. Unrooted phylograms of partial nucleotide sequences of the PB2 and NS genes of selected influenza A viruses including those from poultry in Chile in 2002 (indicated in boxes). Nucleotides 14–188 of PB2and 50–481 of NS were used for the analyses. The lengths of the horizontal lines are proportional to the number of nucleotide differences.
