Characterisation of promoters in the murine gastrointestinal tract. A Schematic overview of the in vivo characterisation, representing the strain design, the animal study and the flow cytometry analysis. 27 mice were divided into 9 groups, with three mice per strain of S. boulardii. B Colonisation across the gastrointestinal tract, as determined from flow cytometry. C Normalised median relative fluorescence intensity of yEGFP across the gastrointestinal tract, from mKate2 + cells. Bar plots are presented as the mean + SD. Points represent the mean of two technical replicates. Faeces data shown here come from samples collected on day 6 of the study
