Throughout the human life, the gut microbiota interacts with us in a number of different ways, thereby influencing our health status. The acquisition of such an interactive gut microbiota commences at birth. Medical and environmental factors including diet, antibiotic exposure and mode of delivery are major factors that shape the composition of the microbial communities in the infant gut. Among the most abundant members of the infant microbiota are species belonging to the Bifidobacterium genus… Expand

Impact of gut-associated bifidobacteria and their phages on health: two sides of the same coin?
TLDR
Current knowledge on the genomics of this diverse bacterial genus, and on the genetic and functional adaptations that have underpinned the success of bifidobacteria in colonising the infant gut are evaluated. Expand
Uncovering Bifidobacteria via Targeted Sequencing of the Mammalian Gut Microbiota
TLDR
Functional predictions of the genes from these reconstructed genomes allows us to identify unique signatures among members of the same bifidobacterial species, highlighting genes correlated with the uptake of nutrients and adhesion to the intestinal mucosa. Expand
Bifidobacterium bifidum: A Key Member of the Early Human Gut Microbiota
TLDR
Current knowledge concerning particular biological characteristics of the B. bifidum species that support its specific adaptation to the human gut and their implications in terms of supporting host health are discussed. Expand
The Response of the Gut Microbiota to Dietary Changes in the First Two Years of Life
TLDR
By 3 years of age, diet and gut microbiota closely resemble those of adults, and Gut bacteria required for the production of SCFAs and secondary BAs are potential targets for the intervention of microbiome-related diseases. Expand
The milk-based diet of infancy and the gut microbiome
TLDR
A paucity of α1, 2 fucosylated oligosaccharides and bifidobacteria in the gut of infants may be associated with poor health. Expand
Bifidobacterial Dialogue With Its Human Host and Consequent Modulation of the Immune System
TLDR
This review is aimed to provide a comprehensive overview on the wide variety of strategies employed by bifidobacteria to engage with the host immune system. Expand
Evolutionary relationships among bifidobacteria and their hosts and environments
TLDR
Looking into the genomic signatures of bifidobacteria strains in different environments can give insights into how this bacterial group adapts to their environment and what types of traits are important for these adaptations. Expand
Bifidobacterial Transfer from Mother to Child as Examined by an Animal Model
TLDR
Findings provide intriguing support for the existence of an unknown route to facilitate bifidobacterial transfer during the very early stages of life. Expand
The impact of human-facilitated selection on the gut microbiota of domesticated mammals.
TLDR
Profile of the metabolic arsenal through metagenomics highlighted extensive functional adaptation of the fecal microbial community of domesticated mammals to changes induced by domestication, and domesticated animals showed, when compared to their feral relatives, increased abundance of specific glycosyl hydrolases. Expand
Deciphering the Bifidobacterial Populations within the Canine and Feline Gut Microbiota
TLDR
The findings show that the intestinal populations of cats and dogs are similar in terms of genus-level taxonomical composition, while at the bifidobacterial species level, clear differences were observed, indicative of host-specific colonization behavior by particular bifIDobacterial taxa. Expand

Diversity of Bifidobacteria within the Infant Gut Microbiota
TLDR
An analysis of pyrosequencing data of PCR amplicons derived from two hypervariable regions of the 16 S rRNA gene revealed a predominance of bifidobacteria in the infant gut as well as a profile of co-occurrence of b ifidobacterial species in the infants’s intestine. Expand
