Colonization of breastfed infants by Bifidobacterium longum subsp. infantis EVC001 reduces virulence gene abundance

Analysis of fecal samples of infants from a randomized open-label trial to determine the effects of supplementing the probiotic Bifidobacterium longum subsp. infantis for the first 21 days finds a significant reduction of gut pathogens (identified by virulence factors) in infants colonized with B. infantis compared to those not fed the probiotic.
