Fig 3. Phylogenetic congruency of Cambodian A(H9N2) viruses.

ML trees were produced for all genomic segments using all Cambodian A(H9N2) viruses detected from 2015 to 2016 and key reference viruses. The phylogenies of the Cambodian viruses have been linked across all eight segments and colour coded according to viral genotype, genotype P viruses are shown in purple and genotype V in green. Viral designations are listed on the left hand side of the HA phylogeny. Incongruence is demonstrated by deviations in topology across the segments and can indicate viral reassortment has occurred. Scale bars are shown below each phylogeny and indicate the number of nucleotide substitutions per site.
