A mother’s gut microbes share genes with bacteria in the infant gut

A mother’s microbiota may shape the infant gut microbiota through horizontal gene transfer, in addition to the classical transmission of maternal bacteria to the infant’s gut.

Christoph Lacroix: “Bifidobacteria are critical for microbiota development in infants”

According to Christoph Lacroix (ETH Zurich), bifidobacteria are critical in the development of the neonatal microbiota. Here's why.

Microbiotas are transmitted between people that spend time together

A recent study suggests that people who spend time together share similar gut microbiotas — with some microbes being largely transmitted between friends and relatives.

A nursing mother’s diet alters the microbiota of her offspring, mouse study finds

The findings of a new research suggest that a mother’s diet during nursing influences her offspring’s microbiota composition, gut health and predisposition to become obese.

L. rhamnosus GG increases Bifidobacteria and reduces inflammation in children with cystic fibrosis, study says

A supplement of LGG would seem to favour the proliferation of Bifidobacterium and the improvement of clinical and immunological response to childhood cystic fibrosis.

COVID-19 in children: nasal microbiota as a possible ‘shield’ protection

Moraxella may be involved in protecting children from COVID-19 infections through its action on amino acid and lipid metabolism in the upper respiratory tract.

Babies acquire multi-drug-resistant bacteria within hours of birth

Antimicrobial resistant bacteria are present in newborns after just a few hours of life and they help to understand the routes of transmission of antibiotic-resistance genes.

Older siblings may influence a child’s microbiota

The findings of a new research suggest that during the early maturation, the microbiota would be more likely to be influenced by other microbiotas on a not-too-distant level of maturity.

Structures of microbial enzymes hint at how these proteins recognize their targets

New research offers insights into how human gut bacteria recognize sulfated glycans. The findings could help to develop interventions for diseases where sulfated glycan metabolism is altered.

Microbiotas of Hadza infants differ from those of infants living in industrialized areas

New research shows that microbiota diversity appears early in infants from nonindustrial populations and could be traced back to their mothers as well as to the local environment.
