Figure 3. Wild-type genes restore ability to endure in the intestine to mutants impaired in colonization.
Two-strain oral infections were carried out comparing each mutant to a gene add-back strain in four mice. qPCR was used to estimate the abundance of each strain. Shown are the log2 (recovered/inoculum) values per mouse for the mutant (closed circles) and the add-back (open circles) strains.
