Identification of S. Typhimurium transposon-insertion mutants with putative niche-specific differences in fitness. (a) A correlation plot showing mutants with differential fitness superimposed on all mutants [
] and those attenuated in both tissues (within the yellow box). Orange dots [
] indicate mutants of genes which were consistently attenuated only in the ileal wall and green dots [
] indicate mutants of genes which were consistently attenuated only in MLNs. (b) A correlation plot highlighting the mutants of the 2 genes selected for validation: ptsN [
] and spvC [
]
