unlike many bacteria, these yeasts demonstrate high survival rates through the GI tract and can assist in stabilizing microbial balance and modulating immunity during infections or chronic illnesses ( Probiotic efficacy is generally measured in colony-forming units (CFU), with typical daily doses ranging from 1 10 9 to 1 10 0 CFU, though clinical benefits are highly dependent on the specific strain or combination of strains, as many effectssuch as the prevention of diarrheal diseasesare strictly strain-specific ( Concurrently, accumulating evidence suggests that several core mechanisms, namely, pathogen inhibition, enhancement of epithelial barrier function, and immunomodulation, are common across multiple taxa, providing a mechanistic foundation for the extensive commercialization of probiotics in dietary supplements, functional foods and beverages, and topical cosmetic formulations worldwide ( 3 Key probiotic microorganisms and their functional characteristics Key probiotic microorganisms in the gut are typically Gram-positive or yeast species that can survive GI transit, transiently colonize the intestine, and interact with the resident microbiota and host tissues ( Figure 1 illustrates the pathway from the isolation of probiotic strains to industrial-scale production
Initial treatment may involve frequent injections followed by maintenance regimens, with periodic review of symptoms and, where appropriate, blood counts
Serious adverse events were similar in incidence between the groups
Week 812 Near-complete healing in many cases
