Figure 2. . . Relative changes in gene abundance before and after travel for each of 122 healthy travelers from the Netherlands during 2010–2012 for genes cfxA (A), tetM (B), tetQ (C), and ermB (D). Increases are shown with white bars on the positive y-axis; decreases are shown in dark gray bars on the negative y-axis. Each bar on the x-axis represents the change in a different study participant. The travel destination regions of the participants are indicated above the graph. No region is indicated for some travelers who either visited >1 of these regions or visited countries that were not in the defined regions (see Table 2).
