Lactobacillus helveticus

Lactobacillus helveticus is a Gram-positive, acid-tolerant, non-spore-forming lactic acid bacterium widely used in dairy fermentation and evaluated as a probiotic. It can colonize the gastrointestinal tract, where it exerts health-promoting functions such as modulating the gut microbiota, increasing production of beneficial short-chain fatty acids, antagonizing enteric pathogens, and attenuating inflammation. Colonization depends on traits like adhesion factors (e.g., S-layer and mucus-binding proteins), exopolysaccharide production, and metabolic adaptability. Its benefits are strain-specific, with select strains notably mitigating diarrheal diseases and favorably altering gut immune responses and barrier integrity
