Figure 1. Inoculation of E. coli Nissle in mice pre-colonized with IBD associated E. coli or a control strain.

Sets of three mice were used in each experiment. CFU of the inoculation suspension of IBD/control strain are shown at day 0 (∼10⁹ CFU/mouse). Blue arrow indicates the inoculation of E. coli Nissle strain at day 6 (∼10⁹ CFU/mouse). Each graph represents the CFU counts of three mice and bars represent Standard error of the means (SEM). Detection Limit (DL) at 20 CFU/g faeces.
