From January 1995 through July 1998, we investigated the occurrence of Cyclospora cayetanensis infection associated with gastrointestinal illness or diarrhea in foreign residents and natives of West Java, Indonesia. We found that C. cayetanensis was the main protozoal cause of gastrointestinal illness and diarrhea in adult foreign residents during the wet season. The parasite rarely caused illn...
Popularization of the acid-fast stain in the early 1980s for detecting Cryptosporidium species in stool specimens set the stage for recognition of Cyclospora species. Between 1986 and 1993, there were nine reports linking diarrheal illness in more than 200 immunocompetent and immunocompromised children and adults to an unidentified, acid-fast organism resembling a "large Cryptosporidium" [2-10]...
Human enteropathogenic microsporidia (HEM), Cryptosporidium parvum, Cyclospora cayetanesis, and Giardia lamblia are associated with gastrointestinal disease in humans. To date, the mode of transmission and environmental occurrence of HEM (Encephalitozoon intestinalis and Enterocytozoon bieneusi) and Cyclospora cayetanesis have not been fully elucidated due to lack of sensitive and specific envi...
In part, Cyclospora cayetanensis owes its recognition as an emerging pathogen to the increased use of staining methods for detecting enteric parasites such as Cryptosporidium. First reported in patients in New Guinea in 1977 but thought to be a coccidian parasite of the genus Isospora, C. cayetanensis received little attention until it was again described in 1985 in New York and Peru. In the ea...
Two large outbreaks of diarrheal illness associated with Cyclospora cayetanensis, a coccidian parasite, provided an opportunity to evaluate clinical syndromes associated with this enteric pathogen. Reiter syndrome, a triad of ocular inflammation, inflammatory oligoarthritis, and sterile urethritis, has been associated with enteric infections. We describe the first case of Reiter syndrome follow...
We describe a pilot study that attempted to infect human volunteers with Cyclospora cayetanensis. Seven healthy volunteers ingested an inoculum of Cyclospora oocysts (approximately 200-49,000 oocysts). The volunteers did not experience symptoms of gastroenteritis, and no oocysts were detected in any stool samples during the 16 weeks volunteers were monitored.
To determine prevalence of Cyclospora cayetanensis infection in Henan, China, we conducted a study of 11,554 hospital patients. Prevalence was 0.70% (95% confidence interval 0.70% ± 0.15%), with all age groups infected. Most cases were found in the summer. Minor sequence polymorphisms were observed in the 18S rRNA gene of 35 isolates characterized.
coccidian protozoa of cyclospora cayetanensis are obligate intracellular apicomplexan parasites that infect the mucosal epithelium of the small intestine of immunocompetent and immunocompromised persons. a 25- years old woman from around, tehran with complaint of faintness and fatigue with hiv positive/aids confirmed eight months ago was admitted in imam khomeini hospital, tehran, iran in 2014....
Cyclospora is recently described new human pathogenic coccidian causing intermittent diarrhoeal enteritis which may persist for weeks or months in immunocompetent subjects, particularly travellers visiting some tropical areas and countries, such as Nepal, the Caribbean, Peru and Mexico. More rarely this enteric pathogen affects immunocompromised humans, namely HIV-infected people or AIDS patien...
