II. Mechanism of Action
II. Mechanism of Action
Saccharomyces boulardii (S. boulardii) is a probiotic yeast that has been found to have numerous beneficial effects on canine health. Its mechanism of action involves several key processes:
A. Colonization and Immune Modulation
- Colonization: S. boulardii colonizes the canine gastrointestinal tract, creating a physical barrier against harmful bacteria and viruses. It occupies receptor sites, preventing pathogens from attaching to the intestinal mucosa.
- Immune Modulation: S. boulardii stimulates the production of immune-boosting cytokines and enhances the activity of immune cells, such as macrophages and dendritic cells. This strengthens the immune system, enabling it to better recognize and eliminate pathogens.
B. Antibiotic-Associated Diarrhea
- Neutralization of Toxins: S. boulardii produces enzymes that neutralize toxins released by Clostridium difficile (C. diff), a common cause of antibiotic-associated diarrhea in dogs. By breaking down these toxins, S. boulardii reduces inflammation and diarrhea.
- Restoration of Gut Microbiota: Antibiotics can disrupt the balance of beneficial bacteria in the gut, leading to diarrhea. S. boulardii helps restore the normal microbiota by supporting the growth of good bacteria while inhibiting harmful ones.
- Adhesion to Gut Mucosa: S. boulardii has a strong affinity for the canine intestinal mucosa. This adhesion forms a protective layer that prevents the attachment of pathogens and promotes the healing of damaged intestinal tissue.
