Effect of a New Probiotic <i>Saccharomyces cerevisiae</i> Strain on Survival of <i>Escherichia coli</i> O157:H7 in a Dynamic Gastrointestinal Model

Abstract

Survival of Escherichia coli O157:H7 was investigated using a dynamic gastrointestinal model. A high bacterial mortality was observed in the stomach and duodenum. In contrast, bacteria grew in the distal parts of the small intestine. The coadministration of Saccharomyces cerevisiae CNCM I-3856 led to a significant reduction of bacterial resumption, maybe through ethanol production.
