Insights

Strongyloides stercoralis infection can cause severe illness in immunocompromised individuals. This case suggests gut bacteria migrating with the parasite cause sepsis in severe Strongyloides stercoralis infestations.

Area of Science:

  • Infectious Diseases
  • Gastroenterology
  • Microbiology

Background:

  • Strongyloides stercoralis (S. stercoralis) is a parasitic nematode prevalent in tropical regions.
  • While often asymptomatic, S. stercoralis can cause hyperinfection and fatal disease in immunocompromised patients.
  • A hypothesis suggests bacterial translocation across the bowel wall contributes to sepsis in severe S. stercoralis cases.

Observation:

  • A 30-year-old man presented with malabsorption syndrome due to S. stercoralis infestation and small bowel bacterial overgrowth.
  • The patient developed severe duodenojejunal ulceration, septicemia, and fatal hypokalemia.
  • Escherichia coli was isolated from both blood and jejunal fluid, exhibiting identical antibiotic sensitivity.

Findings:

  • This case report provides evidence supporting the hypothesis of bacterial migration from the intestinal lumen.
  • Bacterial translocation appears to be a significant factor in the pathogenesis of septicemia during fulminant S. stercoralis infestation.
  • The findings highlight the critical role of Escherichia coli in the fatal outcome.

Implications:

  • Understanding the mechanism of bacterial translocation in S. stercoralis is crucial for managing severe infections.
  • This study underscores the importance of considering bacterial co-infection in immunocompromised patients with S. stercoralis.
  • Further research into preventing bacterial migration could improve outcomes for patients with severe parasitic infections.

Giardiasis01:12

Giardiasis

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...
Amebiasis01:28

Amebiasis

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...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
Inflammatory Bowel Disease II: Ulcerative Colitis01:20

Inflammatory Bowel Disease II: Ulcerative Colitis

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...
