From: Genetic characterization of avian influenza subtype H4N6 and H4N9 from live bird market, Thailand
Phylogenetic analysis of NA gene of Thai H4N9 virus (CU-LM1984) and other N9 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 H4N9 influenza virus characterized in the study is highlighted by triangle.
