Parasitic bowel disease: three pathogens important in primary care
Postgraduate Medicine
|May 1, 1982
Summary
Diagnosing parasitic bowel diseases like giardiasis, amebiasis, and strongyloidiasis requires high suspicion. Early detection and treatment are crucial, especially for immunocompromised individuals at risk of fatal disseminated strongyloidiasis.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Clinical Diagnostics
Background:
- Parasitic infections of the bowel present with diverse gastrointestinal symptoms.
- Accurate diagnosis is often challenging due to varied clinical presentations.
Purpose of the Study:
- To highlight the importance of considering giardiasis, amebiasis, and strongyloidiasis in patients with gastrointestinal complaints.
- To outline key diagnostic considerations for each parasitic infection.
Main Methods:
- Review of clinical presentations and diagnostic approaches for common parasitic bowel diseases.
- Emphasis on patient history, including travel, and specific symptom clusters.
Main Results:
- Giardiasis: Suspect in travelers with unexplained diarrhea, bloating, and flatulence.
- Amebiasis: Consider in persistent diarrhea or inflammatory bowel disease-like symptoms.
- Strongyloidiasis: Suspect with unexplained diarrhea, upper abdominal pain, and eosinophilia, especially in immunocompromised patients.
Conclusions:
- A high index of suspicion and targeted diagnostic methods are essential for parasitic bowel disease diagnosis.
- Prompt investigation is critical, particularly for strongyloidiasis in immunocompromised individuals to prevent fatal disseminated disease.

01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:28Fungal 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...
01:15Diversity of Protists I
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...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:26Inflammatory Bowel Disease I: Introduction
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
