Effect of Bifidobacterium crudilactis and 3'-sialyllactose on the toddler microbiota using the SHIME® model.

The important changes in diet during the first years of life strongly modulate the intestinal microbiota of young children. Among in vitro digestive models, the simulator of human intestinal microbial ecosystem (SHIME®) model, seems particularly adapted to study the effects of prebiotics and/or probiotics on the dynamic microbiota of toddlers. The main purpose of this study was to investigate different formulations with prebiotic (3'-sialyllactose: 3'SL) and probiotic (Bifidobacterium crudilactis FR/62/b/3) effects on young child microbiota using the SHIME® model.
