Abstract
Background: Probiotics are live microorganisms with many health benefits for their host. The intestinal microbiota are the largest source of microbial variation and plays a significant role in host responses in health and disease. However, few studies have assessed the repercussions of probiotics regarding the morphology and immunology of the gastrointestinal tract in animal models. This study was designed to evaluate the effect of administering capsulated Saccharomyces species on gastrointestinal tract properties in rats. Materials and Methods: In this study mice rats were feed with Saccharomyces Boulardii intwo forms of capsulated and free. IgA was measured in duodenal and jejunal washings using ELISA assay according to the manufacturer’s instructions.Results: Probiotic S. boulardii could increase IgA secretion from duodenum and jejunum in comparison with the control group, and this increase was significant in microencapsulated S.boulardii-treated group and in the duodenum of S. boulardii-treated group (PConclusion: It can be concluded that S. boulardii is a potential probiotic yeast with immunostimulatory effects which can be used in the treatment of gastrointestinal disorders.
