Characterization of the Gastrointestinal Microbiota in Newborn Infants

The BABIES study is a single-center, randomized, double-blinded, placebo-controlled study in newborns with a 4-week intervention period from birth to 28 days of life followed by a 2-week follow-up period (Figure 1). The study will evaluate the seeding ability of supplementation with a probiotic strain.

The aim is to investigate the recovery and engraftment of the probiotic strain in infant fecal samples after 4 weeks supplementation using a strain specific quantitative Polymerase Chain Reaction (qPCR).
