Figure 2. Neighbour-joining phylogenetic tree [38] based on a MUSCLE alignment of ITS1 5.8S-ITS2 sequences from Trichuris spp. isolated from human, non-human primates and pigs.

Bootstrap values are indicated as percentages on the branches of the consensus tree which was inferred from 1000 replicates [33]. The tree was rooted with T. ovis and T. discolor. The evolutionary distances were computed using the Tajima-Nei method [32] and the scale represents the number of base substitutions per site. Branches corresponding to Clade DG are highlighted in blue, while branches corresponding to the Clades CP-GOB and T. suis are highlighted in green and pink, respectively.
