Project description:Human milk oligosaccharides (HMOs) are highly diverse complex carbohydrates secreted in human milk. HMOs are indigestible by the infant and instead are metabolized by bifidobacteria in the infant gut microbiome to produce molecules that promote infant health and development. 2´fucosyllactose (2´FL) is an abundant HMO and is utilized by Bifidobacterium longum subsp. infantis, a predominant member of the infant gut microbiome. Currently, there is not a scientific consensus on how or if bifidobacteria metabolize the fucose portion of 2´FL or free fucose. This proteomic analysis was conducted in order to characterize the metabolic pathway by which B. infantis utilizes fucose.
Project description:In a cohort consisting of 32 mother-infant dyads, we profiled the fecal metabolome at birth and at 3 and 6 months of infant age. Metagenomes from the same samples were also generated.
Project description:Microbiota assembly in the infant gut is influenced by time and duration of dietary exposure to breast-milk, infant formula and solid foods.
Project description:Samples from Gates Foundation Sepsis Project testing the effectiveness of probiotic LP2 on preventing infant sepsis in Dhaka, Bangladesh. Samples include infant fecal and serum and mother's milk.
