简要总结
The purpose of this study is to determine if supplementing healthy term infants delivered by C-section or vaginal delivery who only consume breastmilk with a probiotic for 21 consecutive days increases levels of bacteria in infants' stool.
详细描述
The purpose of this clinical trial is to determine the effects of supplementing the probiotic Bifidobacterium longum subsp. infantis for the first 21 days of life in healthy term breastfed infants delivered via C-section or vaginal delivery on gut bacteria composition during, 1 week, and 1 month after supplementation compared with matched-control term infants receiving standard care. The investigators' specific aim is to compare the fecal microbiota (total B. infantis, total Bifidobacterium, total bacteria and composition of microbiota) between the supplement and control groups.

- •Plan to exclusively breastfeed their infants for at least 3 months
- •Infants: 0-7 days old, delivered by C-section or vaginal delivery, born >37 weeks gestation, without medical complications that would preclude breastfeeding or alter gut microbiota
排除标准
