The influence of the biotherapeutic yeast Saccharomyces boulardii (nom. inval.) on Salmonella typhimurium and Yersinia enterocolitica was investigated in vitro . A suspension of 1.4x 10 7 /ml S. typhimurium grew to 6.6x 10 8 /ml within five hours but only to 1.9x 10 8 /ml if coincubated with approximately 10 8 /ml live S. boulardii . A similar suspension of Y. enterocolitica did not multiply at all in the presence of S. boulardii . Furthermore, the invasion of S. typhimurium and Y. enterocolitica was measured in HeLa cell cultures. More than 10% of S. typhimurium and more than 60% of Y. enterocolitica , respectively, could be recovered as viable intracellular organisms at 3 h. After coincubation with S. boulardii , less than 0.1% of S. typhimurium and Y. enterocolitica , respectively, initially added to the monolayers, were intracellular. These in vitro experiments showed that S. boulardii inhibited not only growth of S. typhimurium and Y. enterocolitica but also their invasion into HeLa cells. Nevertheless, the value of S. boulardii for treating diarrhoea caused by these bacteria remains to be shown in vivo . Keywords: Saccharomyces boulardii , bacterial invasion, Salmonella typhimurium , Yersinia enterocolitica .
