Lactobacillus reuteri EBI-03 is a potential probiotic strain that exhibits several beneficial properties for human gut health, including high tolerance to acid and bile, inhibition of potentially pathogenic species, and the production of the antimicrobial agent reuterin.The adhesion ability of L. reuteri EBI-03 to intestinal epithelial Caco-2 cells is being studied to evaluate its potential as a probiotic.[1]L. reuteri EBI-03 can survive the acidic conditions of the stomach and the presence of bile salts in the upper intestine. It also has an affinity for gut mucus and epithelial cells, allowing it to colonize the intestine and exert its beneficial effects.Studies have shown that L. reuteri has potential therapeutic applications, such as reducing the risk of diarrhea in children and preventing bone loss in osteoporosis models.[2]
