Fig 2. Inferred phylogenetic relationship among Trichuris spp. using concatenated amino acid sequences and Maximum Likelihood (ML) and Bayesian Inferences (BI).

The three major groups identified by the phylogenetic tree include primate-, pig- and ruminant- derived Trichuris. Bootstrap frequencies (BF) and posterior probabilities (PP) are indicated on the branches (BF/PP). Scale bar represents the number of substitutions per site.
