Figure 1From: Genetic characterization of avian influenza subtype H4N6 and H4N9 from live bird market, ThailandPhylogenetic analysis of HA gene of Thai H4N6 and H4N9 viruses and other H4N6 and H4N9 influenza A viruses. The phylogenetic tree was generated using the neighbor-joining algorithm. Bootstrap analysis with 1000 replicates and posterior probability from BMCMC analysis were performed for confirming tree topology (Bootstrap, posterior probability). The H4N6 and H4N9 influenza viruses characterized in the study are highlighted by a triangle.Back to article page
