COMMENT: The origin of newborn gut microbiota is investigated in this work. The source of intestinal microbes in newborn is very important because some evidences suggest that this first intestinal bacterial colonization affects later health.

The Bifidobacteria that colonize the gut of the newborn are specially relevant because they seem to play a role in the proctection against susceptibility to diverse diseases later in life. Recent works support that maternal bifidobacteria are an important source of the infant gut microbiota. The fact that the bifidobacterial strains from mother and child are the same strains suggests it.
