Phylogenetic trees of cox1 (A) and nd1 (B) genes of Echinostoma mekongi adults (n = 6) extracted from volunteers and metacercaria (n = 1) extracted from Pila sp. snails for study of E. mekongi infection in schoolchildren and adults, Kandal Province, Cambodia. Sequences from this study (shades boxes) are shown in comparison with other 37-collar-spined Echinostoma spp. (outgroup; Opisthorchis viverrini). The trees were constructed using the maximum-likelihood method, employing the Tamura-Nei model of nucleotide substitution with 1,000 bootstrap replications and viewed in MEGA X (https://www.megasoftware.net). GenBank accession numbers are given for all sequences. Scale bars indicate substitutions per site.
