Development of Human Microbiota01:30

Development of Human Microbiota

5
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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

89.9K
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...

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

7
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

1
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

1
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...

Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

5
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Area of Science:

  • Microbiology
  • Neonatal Research
  • Gastroenterology

Background:

  • Necrotizing enterocolitis (NEC) is a severe complication of preterm birth.
  • Gut microbial communities are implicated in NEC development.
  • Current understanding is limited by study variations and small sample sizes.

Purpose of the Study:

  • To explore the role of gut bacteria in necrotizing enterocolitis.
  • To identify potential protective bacterial species or their products.
  • To inform strategies for preventing NEC in preterm infants.

Main Methods:

  • Utilized direct-from-stool nucleic acid sequencing.
  • Analyzed bacterial community composition in case-control studies.
  • Reviewed existing literature on gut microbiota and NEC.

Main Results:

  • Gram-negative bacteria are increasingly recognized as causative agents of NEC.
  • Protective bacteria have not been consistently identified.
  • Probiotic benefits are not evident in very low birth weight infants (<1000g).

Conclusions:

  • Further research into gut microbes and their products is needed for NEC prevention.
  • Targeting specific microbial modulations may offer a novel therapeutic strategy.
  • Preventing NEC in high-risk preterm infants remains a critical challenge.
