Travelers’ resistomes group significantly by region after travel, and Southeastern Asia and Eastern Africa have the strongest signature. a 95% confidence intervals, odds ratios, and p values for the samples with the same destination being drawn from the same metaresistome. Fisher’s exact tests were done for this comparison within the time point (y-axis). The black vertical line at 1 shows the expected result under the null. Source data for all panels is provided in the source data file (Additional file 3). b The left of this Sankey diagram has models built from the pre-travel samples, and the right has models built from the post-travel samples. Each model has a pie chart that shows the number of samples in the model (total of 190 for each time point), and these pies are divided by destination. The lines connecting the pre- and post-travel models are colored according to region (dark blue is Northern Africa, light blue is Eastern Africa, orange is Southern Asia, and red is Southeastern Asia), and their thickness is proportional to the number of samples that follow that path
