Figure 2. . . . Multilocus sequence typing of Escherichia coli (n = 146) from the post-travel isolates of 133 travelers from the Netherlands. The numbers indicate the most prevalent sequence types (STs). Gray shadow indicates that >1 ST belongs to the same complex. The following sequences belong to STC10: ST4,10, 34, 43, 44, 48, 167, 193, 215, 218, 227, and 617. Thick connecting lines indicate single-locus variants; thin connecting lines indicate variants with 2–3 loci differences; dashed connecting lines indicate variants with 4 loci differences; dotted connecting lines indicate 5–7 loci differences.
