title: Saccharomyces boulardii and bacillus cereus var. Toyoi influence the morphology and the mucins of the intestine of pigs.
abstract: The mode of action of probiotics is still incompletely understood. To study the interactions between probiotic micro-organisms and the host their effects on morphology and mucins of the intestinal mucosa were investigated. Fifteen clinically healthy weaned pigs were divided into three groups and received either Saccharomyces boulardii or Bacillus cereus var. toyoi or were left untreated. Sections of duodenum, proximal and mid jejunum, ileum, caecum, and colon were examined. An increase of villus length in the small intestine and a decrease in the number of goblet cells with 2.6-sialylated mucins in the large intestine were observed in both treatment groups. There were no differences in crypt morphology, number of Ki67-positive cells, total number of goblet cells and number of goblet cells with acidic, neutral, sulphated, or 2.3-sialylated mucins between groups. The results indicate an effect of Saccharomyces boulardii and Bacillus cereus var. toyoi on the intestinal architecture of pigs.
