Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

373
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines

71.2K
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...

What is Monogastric Digestion?

70.4K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

295
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Irritable Bowel Syndrome I: Introduction

219
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Area of Science:

  • Immunology
  • Gastroenterology
  • Microbiome research

Background:

  • Celiac disease (CeD) is an autoimmune condition triggered by gluten ingestion in genetically susceptible individuals.
  • It involves small intestinal villous atrophy and diverse clinical manifestations.
  • Current management relies on a strict gluten-free diet, which has limitations in efficacy and adherence.

Purpose of the Study:

  • To investigate the role of the gut microbiome as a cofactor in celiac disease pathogenesis.
  • To elucidate the mechanisms by which gut microbes may influence CeD development and progression.
  • To identify potential novel therapeutic targets for CeD based on microbiome interactions.

Main Methods:

  • Review of epidemiological studies and clinical associations implicating the gut microbiome in CeD.
  • Analysis of in vitro and in vivo preclinical models to explore microbial mechanisms in CeD.
  • Synthesis of current understanding of host-microbe interactions in the context of CeD.

Main Results:

  • The gut microbiome is increasingly implicated in CeD pathogenesis, beyond genetic predisposition.
  • Preclinical models are beginning to reveal specific mechanisms of microbial influence on CeD.
  • Understanding these mechanisms is crucial for developing targeted interventions.

Conclusions:

  • The gut microbiome represents a significant cofactor in celiac disease.
  • Further research into microbiome-CeD interactions is essential for advancing therapeutic strategies.
  • Targeting the gut microbiome holds promise for future CeD prevention and treatment.
