Description – Bifidobacterium longum subspecies infantis (B. infantis) is well adapted to the infant gut. It has co-evolved with the mother-infant dyad and gut microbiome, partly because of its ability to consume complex carbohydrates found in human milk. B. infantis and its human host have a symbiotic relationship that protects the preterm or term neonate and nourishes a healthy gut microbiota prior to weaning.
Application – B. infantis given in combination with human milk increases B. infantis and decreases Enterobacteriaceae in the faeces. Probiotics containing B. infantis decrease the risk of necrotizing enterocolitis in premature infants.
