Figure 3From: Genetic characterization of 2008 reassortant influenza A virus (H5N1), ThailandPhylogenetic trees of NA genes of Thai H5N1 isolates. The trees were generated using MEGA 4.0 applying the neighbor-joining algorithm. Tree topology was supported by bootstrap analysis with 1000 replicates and posterior probability from BMCMC analysis. The values are shown in parenthesis (NJ/BMCMC). The reassorted 2008 H5N1 viruses are depicted as triangle.Back to article page
