Fig 7. Phylogenetic relationships of the tp0326 types.

tp0326 types are shown for T.p. pertenue and Fribourg Blanc isolates and PNG samples; typing designations are as described in Fig 6. Sequences were first aligned using the Muscle algorithm, using default parameters. The evolutionary history was inferred using the Neighbor-Joining method. The optimal tree is shown, with branch lengths equivalent to the evolutionary distance as indicated by the scale. Evolutionary distance was measured using the number of differences per sequence, with pairwise deletion of gaps. The percentage of replicate trees in which the associated molecular types clustered together in the bootstrap test (1000 replicates) is shown next to the branches. Analyses were conducted in MEGA version 7.0 [32].
