We have recently shown that maternal administration of Lactobacillus rhamnosus GG (LGG) during late pregnancy can have beneficial effects on the early development of infant gut microbiota, promoting a bifidobacteria profile similar to that of a healthy breastfed infant.

Faecal microbial diversity was assessed by terminal restriction fragment length polymorphism using restriction enzymes Sau96I and AluI.

Prenatal administration of Lactobacillus rhamnosus has no effect on the diversity of the early infant gut microbiota. Pediatric Allergy Immunology 2012: 23: 255–258. We have recently shown that maternal administration of Lactobacillus rhamnosus GG (LGG) during late pregnancy can have beneficial effects on the early development of infant gut microbiota, promoting a bifidobacteria profile similar to that of a healthy breastfed infant. It is uncertain, however, whether such probiotic supplementation could influence the diversity of infant gut microbiota.
