Insights

Dientamoeba fragilis is a common parasite in children, but this study found no increased risk for gastrointestinal symptoms. The absence of D. fragilis was paradoxically linked to symptoms like diarrhea and fatigue.

Area of Science:

  • Pediatric Gastroenterology
  • Infectious Diseases
  • Microbiology

Background:

  • Dientamoeba fragilis is frequently detected in children presenting to primary care.
  • This parasite is often suspected as a cause of gastrointestinal illness in pediatric populations.

Purpose of the Study:

  • To investigate the association between Dientamoeba fragilis colonization and the presence of gastrointestinal symptoms in children.
  • To clarify the role of D. fragilis in pediatric gastrointestinal disease.

Main Methods:

  • A cross-sectional study was conducted involving children with gastrointestinal symptoms.
  • Logistic regression analyses explored symptom associations with D. fragilis colonization.
  • A case-control analysis using asymptomatic siblings as controls was performed with conditional logistic regression.

Main Results:

  • Dientamoeba fragilis colonization was found in 55.1% of 107 children studied.
  • Absence of D. fragilis was associated with soft to watery stool, chronic diarrhea, and fatigue.
  • Case-control analysis showed no significant difference in D. fragilis colonization between cases and controls (OR = 1.02).

Conclusions:

  • Dientamoeba fragilis is prevalent in children, irrespective of gastrointestinal symptoms.
  • The study suggests D. fragilis colonization does not elevate the risk for gastrointestinal symptoms in children.
  • Unexpected associations between D. fragilis absence and certain symptoms warrant further investigation.

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Diversity of Protists IV01:27

Diversity of Protists IV

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

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.

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...
