Figure 2From: Genetic characterization of avian influenza subtype H4N6 and H4N9 from live bird market, ThailandPhylogenetic analysis of NA gene of Thai H4N6 viruses (CU-LM1973 and CU-LM1983) and other H4N6 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 influenza viruses characterized in the study are highlighted by a triangle.Back to article page
