A good start in life is important-perinatal factors dictate early microbiota development and longer term maturation

Area of Science:

• Microbiology
• Developmental Biology
• Public Health

Background:

• Maternal health is crucial for offspring development, with the gut microbiota playing a vital role in intergenerational health.
• Perinatal factors like nutrition, antibiotics, and stress impact the maternal gut microbiota, influencing offspring microbial colonization.
• Early-life gut microbiota development is modulated by gestational age and delivery mode, affecting immunity, cognition, and metabolism.

Purpose of the Study:

• To review critical perinatal factors influencing early-life gut microbiota.
• To summarize current knowledge on how perinatal factors shape gut microbiota composition and function.
• To discuss the clinical implications of altered early-life microbiota and potential interventions.

Main Methods:

• This review synthesizes existing research on perinatal factors and early-life gut microbiota.
• It examines the impact of maternal health and environmental exposures during pregnancy and birth.
• Literature search focused on studies investigating the relationship between perinatal exposures and infant gut microbiome development.

Main Results:

• Perinatal factors such as maternal diet, antibiotic exposure, and stress demonstrably alter the maternal gut microbiota.
• Mode of delivery and gestational age are key determinants in the establishment and maturation of the infant gut microbiome.
• Perturbations in early-life microbiota are linked to increased risks of various diseases later in life.

Conclusions:

• Perinatal factors critically shape the early-life gut microbiota, with long-term consequences for offspring health.
• Understanding these influences is essential for developing strategies to promote healthy microbial development.
• Interventions involving probiotics and live biotherapeutics show promise for mitigating negative impacts of microbiota dysbiosis.
