  journal={Food Technology and Biotechnology},
Summary Infectious diarrhoea is associated with a modification of the intestinal microflora and colonization of pathogenic bacteria. Tests were performed for seven probiotic yeast strains of Saccharomyces cerevisiae var. boulardii, designated for the prevention and treatment of diarrhoea. To check their possible effectiveness against diarrhoea of different etiologies, the activity against a variety of human pathogenic or opportunistic bacteria was investigated in vitro. In mixed cultures with S…

In-Vitro Growth Inhibition of Bacterial Pathogens by Probiotics and a Synbiotic: Product Composition Matters
Head-to-head in-vitro pathogen growth inhibition experiments can be used to differentiate products from different categories containing probiotic microorganisms and can support the selection process of products for further clinical evaluation.
The use of probiotics for the prevention of antibiotic associated diarrhea (AAD) and the treatment of Clostridium difficile infections (CDI) has been tested in randomized controlled clinical trials and effective use of Probiotics could decrease patients' exposure to antimicrobials.
The protective effect of probiotics ( Lactobacillus acidophilus and Saccharomyces boulardii) against infections caused by Staphylococcus aureus In vitro and In vivo
The World Health Organization's 2001 definition of probiotics is "live microorganisms which, when administered in adequate amounts, confer a health bene t on the host (1). Probiotic microflora
Saccharomyces cerevisiae var. boulardii as a eukaryotic probiotic and its therapeutic functions
Probiotic microorganisms, such as S.boulardii, are used for different illness indications in both adults and children, and have the capability to penetrate into tissues like the Candida species isable to, hence they are not invasive.
Inhibitory activity of Saccharomyces cerevisiae, Rhodotorulaglutinis and Lactobacillus spp against Escherichia coli isolated from children diarrhea infection
Results show variable effectiveness were observed, Lactobacillus spp had the highest inhibitory activity against E. coli, while Yeast interaction that the highest Inhibitory activity from yeast signal againstE.
Salmonella infection - prevention and treatment by antibiotics and probiotic yeasts: a review.
There is a need for further studies into the potential mechanisms, efficacy and mode of delivery of yeast probiotics in Salmonella infections, including their potential to be opportunistic pathogens and antibiotic-resistant carriers.
Heterologous Expression of the Leuconostoc Bacteriocin Leucocin C in Probiotic Yeast Saccharomyces boulardii
Results showed that antilisterial activity could be added to the arsenal of probiotic activities of S. boulardii, demonstrating its potential as a carrier for therapeutics delivery.
Identification and Growth Characterization of a Novel Strain of Saccharomyces boulardii Isolated From Soya Paste
The experimental findings suggest that the isolated S. boulardii possesses excellent probiotic capacities as a biotherapeutic agent for antidiarrheal and gastrointestinal disorders.


Interaction of Saccharomyces boulardii with Salmonella enterica Serovar Typhimurium Protects Mice and Modifies T84 Cell Response to the Infection
Sb shows modulating effects on permeability, inflammation, and signal transduction pathway in T84 cells infected by ST and an in vivo protective effect against ST infection, and demonstrates that Sb modifies invasive properties of Salmonella.
In vitro evaluation of the binding capacity of Saccharomyces cerevisiae Sc47 to adhere to the wall of Salmonella spp.
Saccharomyces cerevisiae Sc47 (Biosaf) is a commercially available baker's yeast strain (Lesaffre, France) that has been used as a probiotic in animal nutrition. It has been previously reported that
Administration of Pediococcus acidilactici or Saccharomyces cerevisiae boulardii modulates development of porcine mucosal immunity and reduces intestinal bacterial translocation after Escherichia coli challenge.
Probiotics may have the potential to modulate establishment of lymphocyte populations and IgA secretion in the gut and to reduce bacterial translocation to MLN after ETEC infection.
Screening of dairy yeast strains for probiotic applications.
K. lactis showed higher adhesive ability than K. marxianus, K. lodderae, and D. hansenii and was the most attractive to continue study for use as probiotic microorganisms, according to evaluated Yeasts of dairy origin as probiotics.
Adherence of Escherichia coli serogroup 0 157 and the Salmonella Typhimurium mutant DT 104 to the surface of Saccharomyces boulardii
Investigating whether also other enteric bacteria such as entero-haemorrhagic Escherichia coli and the DT 104 mutant of S. Typhimurium have the capacity for binding to the cell wall of Saccharomyces boulardii found that these bacteria do not respond very well to drugs but most of the gastrointestinal infections are caused by them, and could be an excellent alternative for treatment and prophylaxis.
Screening of yeasts as probiotic based on capacities to colonize the gastrointestinal tract and to protect against enteropathogen challenge in mice.
Among the 12 S. cerevisiae strains tested, strain 905 showed the best characteristics to be used as a probiotic as demonstrated by survival capacity in the gastrointestinal tract and protective effect of animals during experimental infections.
Inhibition of Saccharomyces boulardii (nom. inval.) on cell invasion of Salmonella typhimurium and Yersinia enterocolitica
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, indicating the value of the biotherapeutic yeast for treating diarrhoea caused by these bacteria remains to be shown in vivo.

It was shown that in comparison to other methods the agar slab technique, although less sensitive than others, gave most consistent and reproducible results.
Escherichia coli adhesion to Saccharomyces cerevisiae and mammalian cells: role of piliation and surface hydrophobicity
A number of Escherichia coli strains isolated from patients with urinary tract infections, bacteremia, or diarrhea were studied and indicated not only a complexity of bacterial receptors on the eucaryotic cells, but also a multiplicity of bacterial adhesions as expressed by the selectivity of bacterial binding.
