Phylogenetic relationships of equine cyathostomins based on full-length gene sequences. Maximum likelihood tree using bootstrap inference of equine cyathostomins in this study (accession numbers listed in Table 2). Syngamus trachea (KM605251), Strongylus equinus (AP017698), and Strongylus vulgaris (GQ888718) were included as outgroups. * indicates resistance to IVM, MOX, and PYR (p ≥ 0.05). + indicates trending resistance (0.01 ≥ p < 0.05). to IVM, MOX, and PYR. Red boxes indicate the clustering of species presenting resistance.
