Summary
This case report details a Dientamoeba fragilis infection, an uncommon cause of gastrointestinal issues like diarrhea and pain. Diagnosis involves stool analysis, and treatment varies by age, with diiodohydroxyquin for adults and metronidazole for children.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Parasitology
Background:
- Dientamoeba fragilis is a flagellate protozoan causing uncommon gastrointestinal infections.
- Symptoms include diarrhea, abdominal pain, flatulence, nausea, vomiting, fatigue, malaise, and weight loss.
Observation:
- Diagnosis relies on identifying the characteristic binucleate trophozoite in multiple preserved stool samples.
- Co-infection with Enterobius vermicularis (pinworm) is noted, suggesting a potential transmission link.
Findings:
- The case report highlights the diagnostic methods for Dientamoeba fragilis.
- It emphasizes the association with Enterobius vermicularis, a common pediatric helminth.
Implications:
- Accurate diagnosis and timely treatment are crucial for managing Dientamoeba fragilis infections.
- Understanding the link with pinworms may inform prevention and transmission strategies.

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

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...

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...

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.
