Figure 6. Summary of antibiotic-induced proliferation of atEc and its impact on host susceptibility to Vc infection.

Phylogenetically diverse bacterial cells that were originally present in the untreated host are depicted in different colours and shapes. Defective and enhanced colonization of Vc cells are denoted with dotted and solid lines (comma-shaped), respectively. The increased population density of atEc is indicated by the increased number of purple cells.
