Figure 2. Extinction events during second step of experimental evolution.

Figure 2.

From left to right, extinction events for PITR-clones challenged with STR, STRR-clones challenged with PIT, CARR-clones challenged with GEN, and GENR-clones challenged with CAR. Superscript R indicates resistance against the particular antibiotic, as evolved during the first step of the evolution experiment. The following source data is available for Figure 2: Figure 2—source data 1.

Figure 2—source data 1. Count data of extinction events as reported in Figure 2.
Extinct populations were determined by their inability to grow in rich media after 24 hr of incubation at 37 °C.
