Fig. 1: The ICU A. baumannii population.

A The upper panel shows the CRAB clone change model with their isolation rate in the ICU (Created in BioRender. Chen, Y. (2024) BioRender.com/q30i340). The below panel diaplays the comparison of the A. baumannii populations collected in this ICU over the initial (2019) and follow-up (2021) study periods. Horizontal bars are proportional to the number of isolates of given sequence types (STs), which are labelled and represented by different colours. Thinner horizontal lines and labels indicate whether isolates were carbapenem-resistant (CRAB; red) or carbapenem-sensitive (CSAB; blue). B Overview of the spatiotemporal distribution of GC2/ST2 (blue) and ST164 (orange) isolates over the course of the 2021 study. Bed unit and room numbers are indicated on the horizontal axis, and study week numbers are on the vertical axis. The sizes of the circles correspond to the number of isolates collected from each patient/bed unit at each sampling timepoint. Source data are provided as a Source Data file.
