Fig 3. Inferred phylogeny among Trichuris spp. recovered from pigs and primates based on partial cox1 sequences and NJ clustering.

Samples for which the full mitochondrial genome is sequenced are indicated by a solid triangle. The phylogeny identified two major clades for Trichuris in pigs, namely ‘T. suis Europe’ and ‘T. suis China’. Five distinct clades for Trichuris spp. recovered from primates (including humans) were identified, namely ‘T. colobae’, ‘Trichuris sp. GHL’, ‘Trichuris Human Uganda’, ‘Trichuris Human China’, and ‘Trichuris sp. non-human primates’. Scale bar indicates number nucleotide substitutions per site. Only bootstrap values > 70 are given.
