Tap water samples from the toilets of an Italian national railway train were collected over a period of 10 months and tested for the presence of Cyclospora cayetanensis (C. cayetanensis) using EvaGreen® real-time polymerase chain reaction (RT-PCR) assay coupled with high resolution melting (HRM) analysis for protozoan detection and oocyst quantification. C. cayetanensis positive samples were de...
Because the lack of typing tools for Cyclospora cayetanensis has hampered outbreak investigations, we sequenced its genome and developed a genotyping tool. We observed 2 to 10 geographically segregated sequence types at each of 5 selected loci. This new tool could be useful for case linkage and infection/contamination source tracking.
The coccidian parasite Cyclospora cayetanensis is recognized as an emerging pathogen that causes protracted diarrhea in humans. The first cases of Cyclospora infection were reported in the late 1970s and were observed among expatriates and travelers in regions where infections are endemic. Since then, Cyclospora has been considered a cause of traveler's diarrhea. Epidemiological investigations ...
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...
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....
BACKGROUND Cyclospora cayetanensis, a coccidian parasite, has increasingly been recognized as a cause of gastrointestinal tract illness. We describe an outbreak of Cyclospora infection following a wedding reception. OBJECTIVES To investigate and characterize risk factors associated with the outbreak of Cyclospora and to describe the observed clinical course and spectrum of illness. METHODS ...
This is the first case of human cyclosporiasis reported in Korea. We detected the oocyst of Cyclospora cayetanensis from a 14-yr old girl who complained of persistent diarrhea after traveling to Indonesia. Round oocysts sized about 8 to 9 m with wrinkle on the wall were found in modified acid fast stained stool specimen. Stainability was variable from red to pale. Oocyst wall showed typical aut...
Cyclospora cayetanensis is a coccidian agent of chronic diarrhea in humans with a worldwide distribution. We report the first documented case of acquired Cyclosporiasis in Italy. The patient was an immunocompetent woman with no recent history of travel outside the country. Microscopy detected Cyclospora oocysts in a feces sample. PCR detected the pathogen in a second sample, which had tested ne...
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.
