Insights

The early development of the gut microbiota in newborns is crucial for long-term health. This review explores various factors influencing the establishment of the intestinal microbial ecosystem in early life.

Area of Science:

  • Microbiology
  • Human Physiology
  • Developmental Biology

Background:

  • The human intestinal microbiota is essential for normal physiology.
  • Disruptions in gut microbiology are linked to numerous health and disease issues.
  • Newborns are initially sterile, requiring microbial colonization from birth.

Purpose of the Study:

  • To provide a comprehensive overview of factors influencing intestinal microbiology in early life.
  • To highlight the importance of early microbial colonization for host health.
  • To understand the dynamics and determinants of infant gut microbiota development.

Main Methods:

  • Literature review of existing research on infant gut microbiota.
  • Synthesis of current knowledge on factors affecting microbial colonization.
  • Analysis of host and environmental influences on early microbial ecosystems.

Main Results:

  • The first colonizers significantly shape the developing gut ecosystem.
  • Host characteristics and diet are key determinants of microbial development.
  • Other contributing factors can also profoundly impact early microbial composition.

Conclusions:

  • Understanding the factors that shape the infant gut microbiota is critical for promoting health.
  • Early life microbial development influences immune, metabolic, and neurological systems.
  • Further research into these determinants can inform interventions for gut health.

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
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 small...

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...

Introduction to the Human Microbiota

Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity, and disease...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Microbiota of the Stomach and Small Intestine01:27

Microbiota of the Stomach and Small Intestine

The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...
Microbiota of the Large Intestine01:27

Microbiota of the Large Intestine

The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
