The gut microbiota has long-term effects on host health especially in early life. Infants receive maternal faecal microbes during vaginal birth, which is prevented by C-section. C-section is associated with increased risk of many chronic diseases, likely because of the disturbed gut microbiota. We recently showed the effectiveness of a faecal microbiota transplant from the infant's own mother in restoring normal gut microbiota in C-section born infants. However, FMT contains a large diversity of unknown microbes, some of which may pose a risk of dangerous infection. A safe and widely applicable infant microbiota restoration method is urgently needed. In this project, we develop a selective microbiota transplant from mother to infant and test its efficacy and safety in a clinical trial. The work is conducted in the Faculty of Medicine, University of Helsinki.
