Effect of a fermented formula on thymus size and stool pH in healthy term infants.

To investigate the effects of fermented formula (FF) with Bifidobacterium breve C50 and Streptococcus thermophilus 065 on thymus size and stool pH of healthy term infants, ultrasound examinations and evaluations of thymus sizes and thymus indices (TI) and measurements of stool pH were performed in the same 90 term neonates on the 3rd d of life and on the 1st, 2nd, 3rd, and 4th mo of life. Thirty newborns were exclusively breast-fed while the remaining 60 were randomly assigned to receive either a FF or a standard formula (SF). The fecal pH of the breast-fed group was lower than the SF group (p < 0.
