The probiotic Saccharomyces boulardii exerts beneficial effects in humans, which include trophic effects, anti-inflammatory effects, antisecretory effects, inhibition of toxins, immunostimulatory effects, and resistance to bacterial overgrowth. This short communication discusses the interactions of the probiotic with brush border membrane (BBM) constituents because most of these effects are BBM mediated. The use of bacterial and yeast probiotics has increased dramatically in more and more clinical states, but their exact mechanisms of action remain largely unknown. The present communication focuses on the interactions of a confirmed yeast probiotic (S boulardii) on the constituents of BBMs.

This study investigates how microbiome colonization influences the development of intestinal type 3 immunity in neonates. The results showed that reduced oxygen levels in the small intestine of neonatal rats induced by Saccharomyces boulardii accelerated microbiome colonization and type 3 immunity development, which protected against Salmonella enterica serovar Typhimurium infection. Microbiome maturation increased the abundance of microbiome-encoded bile salt hydrolase (BSH) genes and hyocholic acid (HCA) levels.

The gut microbiome, a collection of gut microorganisms, is crucial in the development and progression of inflammatory bowel diseases (IBD). Therefore, diet and dietary interventions are promising strategies to shape the gut microbiota for IBD management. Of all the diets studied in the IBD field, the Mediterranean diet has the least restrictive nature, promoting long-term adherence.

Background: Perturbations of intestinal serotonergic neurotransmission seem to be involved in bowel dysmotility associated with irritable bowel syndrome (IBS) with diarrhea. Oral administration of probiotics is an emerging strategy to improve IBS symptoms, possibly via influencing local serotonin metabolism and neurotransmission. In the present study, we evaluated the effects of the yeast Saccharomyces boulardii CNCM I-745 (S.

Oral administration of therapeutic peptides is limited by poor intestinal absorption. Use of engineered microorganisms as drug delivery vehicles can overcome the challenges faced by conventional delivery methods. The potential of engineered microorganisms to act synergistically with the therapeutics they deliver opens new horizons for noninvasive treatment modalities.
