|July 1, 1974
Summary
Cholera disrupts the small intestine's absorptive cells, causing structural damage and cellular changes. These electron microscope findings reveal pathological alterations in epithelial cells, impacting intestinal function.
Area of Science:
- Gastroenterology
- Microbiology
- Cell Biology
Background:
- Cholera, caused by Vibrio cholerae, is a severe diarrheal disease.
- Understanding the cellular mechanisms of cholera is crucial for developing effective treatments.
Purpose of the Study:
- To investigate the ultrastructural changes in the small intestinal mucosa of cholera patients.
- To elucidate the pathological alterations at the cellular level during cholera infection.
Main Methods:
- Electron microscopy was used to examine small intestinal biopsies from six cholera patients.
- Rectal swabs were cultured to confirm Vibrio cholerae infection.
Main Results:
- Absorptive cells exhibited pseudopod-like projections and damaged microvilli.
- Epithelial cells showed mitochondrial swelling, Golgi apparatus changes, and endoplasmic reticulum dilation.
- Interepithelial spaces in the jejunal mucosa were widened, and cytoplasmic fragments were observed in the lumen.
Conclusions:
- Cholera infection induces significant pathological changes in the small intestinal mucosa.
- These findings suggest potential fluid transport alterations and cellular damage contributing to cholera's pathophysiology.

01:20Histology of the Gastrointestinal (GI) Tract
The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

01:25Mucosal Barrier of the Stomach
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

01:27Histology of the Small Intestine
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

01:26Histology of the Large Intestine
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
