Stool consistency data. All mice that did not receive C. difficile had normal stools throughout the study. In contrast, only 13% of mice in the Vehicle/C. difficile treatment group had normal stools on day 12, while 67% of the BC30 treated mice still had normal stools. On days 13 and 14, altered stool consistency was seen in both C. difficile treatment groups. However, evidence of a normal stool was seen in 24% of BC30 treated mice on day 16, but no vehicle treated animals (0%) showed a normal stool consistency on that day. Statistical significance (* p < 0.05) between the vehicle and BC30 treatment groups was found on study days 12 and 16.
