  1. Note: Evolutionary distances between Trichuris spp. from eight non-human primates included in this study are highlighted in boldface for ITS- and cox1-based estimates, respectively. Given almost identical nucleotide sequences of both ITS and cox1 genes in either worms or eggs from the same host species, eight representative specimens were used to calculate evolutionary distances using a maximum composite likelihood model
