Insights

Cyclospora is a rare cause of gastroenteritis. This case highlights the importance of parasitologic examination in persistent diarrhea, identifying Cyclospora oocysts after travel and consumption of contaminated water.

Area of Science:

  • Medical Parasitology
  • Infectious Diseases
  • Gastroenterology

Background:

  • Cyclospora spp. are coccidian parasites causing rare gastroenteritis.
  • The first reported case in Turkey was in 1998 in an AIDS patient.

Observation:

  • A patient presented with ten days of diarrhea, abdominal pain, and nausea.
  • Travel history included the Black Sea region with consumption of muddy, cloudy water.
  • Initial stool microscopy and bacterial cultures were negative for enteropathogens.

Findings:

  • Parasitologic examination revealed Cyclospora oocysts.
  • The patient responded well to cotrimoxazole treatment.
  • Repeated stool examinations were negative for pathogens post-treatment.

Implications:

  • This case underscores the significance of parasitologic stool examination in diagnosing prolonged diarrhea.
  • Cyclospora should be considered as a potential causative agent, especially after travel and exposure to non-potable water.
  • Timely diagnosis and treatment of cyclosporiasis can prevent prolonged gastrointestinal symptoms.

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...
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...
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...
Fungal Phylum Microsporidia01:28

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 I01:15

Diversity 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...
Reservoir of Infection01:30

Reservoir of Infection

Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
