Infant Microbiota Restoration With Maternal Microbes

The goal of this clinical trial is to test the ability of different bacterial products in restoring natural gut microbiota in C-section born infants. The main question it aims to answer is: Do maternally derived strains of bacteria perform better than commercially available probiotic strains in restoring the gut microbiota of C-section born infants? Researchers will compare the gut microbiota of treated infants to that of untreated C-section born infants and untreated vaginally born infants to see if the bacterial treatments cause the microbiota to resemble that of vaginally born infants. Participants will be given a bacterial product orally once daily for either one or four weeks and be asked to collect faecal, urine and saliva samples.
