Insights
Bifidobacteria are crucial for infant health, impacting development and gut microbiota. This review explores their role, influencing factors, and probiotic potential in newborns and infants.
Area of Science:
- Microbiology and Gut Health
- Infant Development and Nutrition
Background:
- Bifidobacteria are dominant gut microbes in healthy breastfed infants.
- Their composition and quantity are vital for infant health and development.
- Reduced bifidobacteria levels are linked to infant diseases.
Purpose of the Study:
- To review bifidobacterial composition and function from birth.
- To describe perinatal factors influencing bifidobacteria.
- To explore implications for infant health alterations and probiotic applications.
Main Methods:
- Compilation of existing scientific literature.
- Analysis of studies on perinatal factors affecting bifidobacteria.
- Review of pre-clinical and clinical trials of Bifidobacterium probiotics in neonates.
Main Results:
- Bifidobacteria play a critical role in early life gut microbiota.
- Various perinatal factors significantly impact bifidobacterial colonization and levels.
- Alterations in bifidobacteria are associated with infant health issues.
Conclusions:
- Bifidobacteria are essential for healthy infant gut microbiome development.
- Understanding their dynamics is key to addressing infant health concerns.
- Bifidobacterium strains show promise as probiotics for neonates.
Abstract:
Bifidobacteria are among the predominant microorganisms during infancy, being a dominant microbial group in the healthy breastfed infant and playing a crucial role in newborns and infant development. Not only the levels of the Bifidobacterium genus but also the profile and quantity of the different bifidobacterial species have been demonstrated to be of relevance to infant health. Although no definitive proof is available on the causal association, reduced levels of bifidobacteria are perhaps the most frequently observed alteration of the intestinal microbiota in infant diseases. Moreover, Bifidobacterium strains have been extensively studied by their probiotic attributes. This review compiles the available information about bifidobacterial composition and function since the beginning of life, describing different perinatal factors affecting them, and their implications on different health alterations in infancy. In addition, this review gathers exhaustive information about pre-clinical and clinical studies with Bifidobacterium strains as probiotics in neonates.

Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
