Bifidobacterium infantis

Restoring Bifidobacterium infantis can allow downstream SCFA-producing bacteria to resume butyrate production. Bifidobacterium infantis is described as a keystone strain in neonatal gut development. In adults, Bifidobacterium infantis acts as a primary fermenter of dietary fibers. Poor fiber tolerance may reflect absence of organisms capable of initial fermentation rather than intolerance to fiber itself. The primary fermentation function of Bifidobacterium infantis is presented as important for patients who tolerate high-fiber dietary changes poorly.
