Microbiota supplementation with Bifidobacterium and Lactobacillus modifies the preterm infant gut microbiota and metabolome

C. Alcon-Giner, M. Dalby, S. Caim, J. Ketskemety, A. Shaw, K. Sim, M. Lawson, R. Kiu, C. Leclaire, L. Chalklen, M. Kujawska, S. Mitra, F. Fardus-Reid, G. Belteki, K. Lloyd, , L. J. Hall

This study shows that supplementing preterm infants with Bifidobacterium and Lactobacillus changes their gut microbiota and increases fecal acetate and lactate levels, resembling a full-term infant's gut environment.
