Can taking Enterol for a long time cause ringworm of the mouth or digestive system?

No, the strain of Saccharomyces boulardii, which contains Enterol, does not cause oral mycosis or food wrap. It is a probiotic strain. The mechanism of action of probiotics consists in the displacement of pathogens, competition for nutrients, inhibition of xin secretion and coaggregation with pathogenic microorganisms. Very rare cases of fungeemia (and positive results of blood cultures detecting strains of Saccharomyces) and sepsis have been reported, mainly among patients with a catheter inserted into the central vein, in critical condition or with significantly weakened immunity. In most cases, the effect was satisfactory after discontinuation of Saccharomyces boulardii, antifungal therapy and removal of the cannula as needed.
