Figure 2. Phylogenetic analyses of the 456 carboxyl-terminal nucleotides of the N gene sequences of isolates obtained from 45 measles case-patients from November 2008 through May 2009, Taiwan. The respective accession number for each sequence is shown in parentheses following the strain name. Boldface italics indicate World Health Organization reference strains. The unrooted neighbor-joining consensus tree was generated by bootstrap analysis of 1,000 replicates by using MEGA4 software (www.megasoftware.net). Scale bar indicates nucleotide substitutions per site.
