Genes required for growth in LB and for GI colonization. Transposon mutant libraries were screened in a mouse model of GI colonization. n = 3 for inputs and outputs for each strain. (A) Shared and unique essential genes for each strain. (B) Shared and unique genes for which transposon insertions resulted in reduced fitness in the gut. Genes had a log₂ fold change less than −2 and a false discovery rate <0.05.
