Insights

Mucoid enteropathy (ME) in rabbits is linked to cecal dysbiosis, with young rabbits experiencing spontaneous cecal hyperacidity. This leads to initial symptoms and later mucus issues due to persistent microbial changes.

Area of Science:

  • Veterinary Microbiology
  • Rabbit Pathology

Background:

  • Mucoid enteropathy (ME) is a significant gastrointestinal disease in rabbits.
  • Understanding the microbial shifts in the cecum is crucial for diagnosing and treating ME.

Purpose of the Study:

  • To investigate the cecal microbial changes associated with mucoid enteropathy (ME) in rabbits.
  • To explore the role of cecal hyperacidity in the pathogenesis of ME.

Main Methods:

  • Microscopic examination of cecal contents from normal and ME-affected rabbits.
  • Experimental induction of cecal hyperacidity in fistulated rabbits.
  • Cecal pH measurements in young and adult rabbits.

Main Results:

  • Rabbits with ME exhibited significant cecal dysbiosis, including loss of protozoa and gram-positive organisms, and an increase in gram-negative organisms.
  • Experimentally induced hyperacidity mimicked the dysbiosis seen in natural ME cases.
  • Young rabbits naturally had lower cecal pH, predisposing them to microbial changes.

Conclusions:

  • Spontaneous cecal hyperacidity in young rabbits likely causes initial ME symptoms like diarrhea and distention.
  • Persistent dysbiosis and subsequent microbial shifts are implicated in late ME manifestations such as mucus hypersecretion and impaction.

Microbiota of the Stomach and Small Intestine

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

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...

Dysbiosis of the Gut Microbiota

The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
