Competing Interests

This work was partly supported by a grant from Biocodex, France, which initiated research on Sacchromyces boulardii. However the funding ended long before the authors were able to identify the active compound described in the paper. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
