Fig 1. Phylogenetic comparsion based on nucleotdie sequences of PB1, PB2, PA, HA, NP, NA, MP and NS genes with that of WHO candidate vaccine (marked with #) and reference strains, Malaysian influenza B/Phuket/3073/2013-like viruses and unique reassortants (marked in black circles), and strains from different countries (in italic).

Phylogenetic trees were reconstructed by maximum likelihood (ML) method with 1,000 bootstrap replicates using PAUP 4.0. Bootstrap values ≥60 are shown. Scale bar represents a genetic distance of 0.01 substitutions/site.
