Fig. 5: Comparative sequence analysis and proportion of Trichuris infection among the four countries.

a Pairwise comparison of sequence similarity between human samples (x-axis) from the four countries and reference sequences (y-axis). The reference sequences were clustered based on pairwise nucleotide identity values using the Ward clustering method. Sequences generated in this study were clustered separately by country using the same method. b Prevalence of mono- and mixed infections comprising human-infecting Trichuris trichiura and Trichuris incognita, stratified by country.
