Supplementary Figure 1. Food inducible IVRC. Prior to oral administration of 1010 CFU EcN, harboring
either plasmids (A) pHL302 (ParaBAD) or (B) pHL303 (PrhaBAD), respectively, mice were supplied with a
diet free of L-arabinose and L-rhamnose. This diet was exchanged against standard food at time 0 for
24 hrs. The return to plant component free diet is indicated by the dotted line. Non-invasive imaging of
mice was used to follow the light emission from intestinal bacteria (thin lines represent individual mice,
thick lines indicate arithmetic means). Bioluminescence signals of the abdominal region were quantified.
One of three experiments with similar results is displayed.
