Venn diagrams of the number of overlapping genes that were present in the genomes (A), over-represented Tn-insertion mutants (B) and under-represented Tn-insertion mutants (C) across all strains in this study. Over-represented and under-represented Tn-insertion mutants were determined using a Log₂ fold change of 2 or -2, respectively, and a q value of less than 0.05. Note, the number of genes associated to C. coli CCN182 are decreased from the numbers written in Table 2 due to the removal of collapsed gene families with more than one locus tag associated
