Figure 1. Patient origin and sampling time of genome sequenced P. aeruginosa DK2 isolates.

The collection of 55 P. aeruginosa isolates of the DK2 clone type was sampled from 21 different CF patients over 38 years. Bacterial isolates are indicated by symbols, and if multiple isolates were sampled the same year from a patient, they are represented by stacked symbols. The isolates are named from the patient from whom they were isolated, and their isolation year (e.g. isolate CF173-1991).
