In adult individuals, the intestinal microbiota comprises several hundred, mostly anaerobic, bacterial species. This complex ecosystem is formed through the successive establishment of different bacteria in infancy and early childhood. Facultative and aerotolerant bacteria establish first, followed by more and more strict anaerobes. The bacteria derive from different sources and the colonization pattern is influenced by delivery mode and environmental factors. Commensal microbes provide the…

Intestinal Microbiota and Aging
TLDR
Here is to make a summary on the recentings of the intestinal microbiota and the application of probiotics in the elderly, to generate due attention to the related research.
Early development of intestinal microbiota: implications for future health.
Gut Microbiota in Human Health and Diseases
Usefulness of Probiotics for Neonates
TLDR
The composition of gut microbial communities was originally known through culture-based studies, which estimated that 400 to 500 different species are present in the adult human intestinal tract, but through the most recent culture-independent analyses the composition is thought to comprise up to 1000 bacterial species per individual and over 5000 species in total.
Programming infant gut microbiota: influence of dietary and environmental factors.
Microbial Colonization From the Fetus to Early Childhood—A Comprehensive Review
TLDR
The most debatable topics during microbial seeding and possible future treatment approaches will be highlighted in this review.
The gut microbiota and its potential role in obesity.
TLDR
The objective of this review is to critically analyze the vast information available on the composition, function and alterations of the gut microbiota in obesity and explore the future prospects of this research area.
Infant Gut Microbiota: Developmental Influences and Health Outcomes
TLDR
The development and integrity of gut microbial communities during infancy may have implications for primate developmental trajectories after weaning, particularly in relation to metabolic and immune functioning later in life.
Gut and Breast Milk Microbiota and Their Role in the Development of the Immune Function
TLDR
Adequate colonization must occur in the immediate postpartum period for the appropriate mucosal immune response since it is apparent that later attempts at colonization do not have the same impact.

TLDR
An overview of the evidence gathered through randomized clinical trials, reviews, and meta-analyses on probiotics and prebiotics in commonly studied conditions in the pediatric population is provided, noting safety and gaps in clinical evidence.

Diversity of the Human Intestinal Microbial Flora
TLDR
A majority of the bacterial sequences corresponded to uncultivated species and novel microorganisms, and significant intersubject variability and differences between stool and mucosa community composition were discovered.
Factors Influencing the Composition of the Intestinal Microbiota in Early Infancy
TLDR
The most important determinants of the gut microbiotic composition in infants were the mode of delivery, type of infant feeding, gestational age, infant hospitalization, and antibiotic use by the infant.
INTESTINAL COLONIZATION OF BREAST‐FED CHILDREN IN A RURAL AREA OF LOW SOCIOECONOMIC LEVEL *
TLDR
This report deals with the intestinal colonization of breast-fed village children studied in their own environment by means of a design that retains at a minimum disturbance of the customs and living conditions of the inhabitants, and concerns the anaerobic and facultative flora, with some emphasis on the E. coli group.

The gut flora as a forgotten organ
TLDR
The flora has a collective metabolic activity equal to a virtual organ within an organ, and the mechanisms underlying the conditioning influence of the bacteria on mucosal homeostasis and immune responses are beginning to be unravelled.
Reduced Enterobacterial and Increased Staphylococcal Colonization of the Infantile Bowel: An Effect of Hygienic Lifestyle?
TLDR
It is shown that some “traditional” fecal bacteria are acquired late today especially in cesarean section–delivered infants, probably due to limited environmental circulation, and skin bacteria like staphylococci have become the first gut colonizers.

Intestinal microbiota and immunoglobulin E responses in 5‐year‐old Estonian children
TLDR
This work has demonstrated differences in the intestinal microbiota between allergic and non‐allergic children, and these differences can be related to environmental factors, like changes of microbial pressure.
