简要总结
The purpose of this study is to determine if supplementing healthy term infants delivered vaginally who consume breast milk, formula, or both with a probiotic for 21 consecutive days increases levels of bacteria in infants' stool.
详细描述
The purpose of phase 1 of this two phase clinical trial is to determine: 1) the effect of decreasing levels of human milk oligosaccharides on fecal B.infantis during and after 21 days of supplementation with Evolve activated B.infantis using exclusively breastfed, mixed-fed and exclusively formula-fed infants; 2) determine the effect of Evolve activated B.infantis on fecal B.infantis levels in exclusively breastfed infants compared to pre-supplementation levels.

研究组 & 干预措施
Mixed fed
Mixed feeding is defined at screening as infants who consume a combination of infant formula and breast milk between day 7 of life through the end on the Lead-in period. Infants will consume B. infantis for twenty-one consecutive days.
干预措施: Bifidobacterium (Dietary Supplement)
Exclusively formula fed
Exclusive formula feeding is defined at screening as infants who consume only infant formula between day 7 of life through the end on the Lead-in period. Infants will consume B. infantis for twenty-one consecutive days.
干预措施: Bifidobacterium (Dietary Supplement)
Exclusively breastfed
Exclusive breastfeeding will be defined at screening as infants who have not consumed any infant formula after 7 days postnatal and have been exclusively breastfed without formula between day 7 of life through the end on the Lead-in period. ). Infants will consume B. infantis for twenty-one consecutive days.
干预措施: Bifidobacterium (Dietary Supplement)
