Microbiome Overview
- The gut microbiome, not just in the gut but all over the body, is a dense, dynamic ecosystem.
- It consists of trillions of microbial cells, including bacteria, archaea, eukaryotes, fungi, and viruses.
Microbiota Variability
- Microbiota vary along the digestive tract due to differing environments like pH, oxygen levels, and nutrient availability.
- Stomach and small intestine communities are less dense than the colon's, which is the most studied due to easy access via stool.
Early Microbiome Development
- A newborn's gut microbiome develops rapidly after birth, influenced by birth method, breastfeeding, pets, and antibiotic exposure.
- Early colonization can significantly impact long-term immune and metabolic development.
