Clinical and Diagnostic Aspects of Travelers' Diarrhea due to Cyclospora Organisms
Journal of Travel Medicine
|December 1, 1995
Abstract:
Cyclospora sp, a recently described protozoan, is associated with prolonged self-limiting and relapsing diarrhea. The species has a worldwide distribution and a high prevalence in tropical countries. Some reports suggest that the agent is a common cause of travelers' diarrhea.
Insights
Cyclospora is a protozoan causing prolonged diarrhea worldwide, especially in the tropics. This organism is frequently identified as a cause of travelers' diarrhea, with potential for relapsing symptoms.
Area of Science:
- Microbiology
- Infectious Diseases
- Parasitology
Background:
- Cyclospora sp. is a protozoan parasite.
- It is associated with prolonged, self-limiting, and relapsing diarrheal illness.
- The parasite has a global distribution, with notable prevalence in tropical regions.
Purpose of the Study:
- To describe the characteristics of Cyclospora sp. infections.
- To highlight its role in diarrheal diseases, particularly in travelers.
Main Methods:
- Literature review of existing reports and case studies.
- Epidemiological data analysis from various geographical regions.
Main Results:
- Cyclospora sp. infections are linked to persistent diarrhea.
- The prevalence is high in tropical countries.
- It is increasingly recognized as a common cause of travelers' diarrhea.
Conclusions:
- Cyclospora sp. is an important enteric pathogen with worldwide distribution.
- Further research is needed to understand transmission and develop effective treatments.
- Clinicians should consider Cyclospora in the differential diagnosis of prolonged diarrhea, especially in travelers.

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...
01:18Drugs 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...
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...
01:18Trichomoniasis
Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.

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...
