Figure 4. Liver abscesses arise from distinct bacterial populations.

(A) A schematic of the experimental setup is shown. Single abscesses were dissected and separately processed for analysis of barcode frequencies to determine if abscesses in the same animal arose from similar or distinct populations. The panels on the left (B, D, F), where dominant barcodes are highlighted in red, correspond to the reference for the graphs on the right (C, E, G). These barcodes are then identified on the panels on the right (C, E, G). Very few dominant red barcodes in (C), (E), and (G) indicate that populations within individual abscesses are distinct.
