Phylogenetic tree based on whole genome sequences. Sequences newly determined for this study are highlighted in color, followed by the cox1 haplotype number and the SSU HVR-I and HVR-IV haplotypes in parentheses. The colors indicate the provinces: red, Chiang Mai; blue, Lamphun; green, Lampang; grey, Mae Hong Son; yellow, Tak. For comparison, selected published S. stercoralis whole genome sequences described in recent whole genome-based S. stercoralis phylogenies are shown (not highlighted). Samples ending with “cam” are from Cambodia [16]. Samples starting with “My” and “Rk” are from Myanmar and Japan, respectively [23]. Sample cn-379 is from southern China [20]. sste_f1_ERR422406 is a free-living female of the S. stercoralis reference isolate [42]. If listed in the corresponding reference, the SSU HVR-I and HVR-IV haplotypes are indicated in parentheses (note that HVR-IV haplotype C in [20] is the same as HVR-IV haplotype E in [12]; this was noticed by Barratt et al. [22] and occurred because the two publications appeared almost simultaneously). Key for comparing samples from Cambodia with figure 4 of [20]: sste3_cam to sste26_cam correspond to Kh-3 to Kh-26; sste_DC51FLfemale1_cam = Kh-27; sste_DC51FLfemale2_cam = Kh-28; sste_DC51FLmale1_cam = Kh-29; sste_DC51FLmale3_cam = Kh-30; sste_DC69FLmale1_cam = Kh-31; sste_DC69FLmale3_cam = Kh-32; sste_DC69FLmale4_cam = Kh-33
