Saccharomyces boulardii (nom. inval.) strain:unisankyo Genome sequencing. Saccharomyces boulardii (nom. inval.) strain:unisankyo

Sb is a tropical strain of yeast that is thermophilic and mostly non-pathogenic to humans. It was first isolated from the skin of lychee and mangosteen fruits in 1923 by the French scientist Henri Boulard in the Indo-China region, and has since then shown to be effective as a preventive and therapeutic agent for diarrhea and other gastrointestinal (GI) disorders caused by the administration of antimicrobial agents.
