An outbreak of cyclosporiasis occurred in attendees of a wedding reception held in Philadelphia, Pennsylvania, on June 10, 2000. In a retrospective cohort study, 54 (68.4%) of the 79 interviewed guests and members of the wedding party met the case definition. The wedding cake, which had a cream filling that included raspberries, was the food item most strongly associated with illness (multivari...

epithelium, we believed this organism to be a Cyclospora sp. rather than a Cystoisospora sp. We searched the serum bank of the Division of Parasitic Diseases, Centers for Disease Control and Prevention, and identified a serum sample from a person with a case of C. cayetanensis cyclosporiasis. An indirect immunofluorescence test was performed by using this serum on a deparaffinized section of th...

results the stool samples were examined via direct microscopic examination and acid-fast staining. positivity was determined in 129 (5.7%) cases. in the overall assessment of the patients with respect to general body itching, rectal itching, allergy, immunosuppression plus cancer, shortness of breath, ulcerative colitis, diarrhea, abdominal pain, salivation, constipation, nausea, vomiting, grow...

Previous reports of diarrhea resulting from Cyclospora species have been linked to travelers and immunocompromised patients. We conducted a prospective study of 1,042 formalin-ethyl acetate fecal concentrates collected from patients with diarrhea. Between May and November 1993, we identified three patients for whom studies were positive for nonrefractile spherical organisms measuring 10 microns...

356 Letters coordinating system among agencies at all levels and deal with the threat of widespread , multistate/international foodborne outbreaks caused by infectious or toxic agents. To the Editor: Human infection with the parasitic protozoa, Cyclospora, was first described in 1979 (1), and the organism was only recently categorized as an important gastrointestinal parasite. A single species,...

While health officials were understandably reluctant to implicate any specific food, others immediately observed that in the previous two years, approximately 2,500 North Americans had been stricken with cyclospora, almost exclusively linked to the consumption of fresh raspberries from Guatemala, and at almost the exact same time of year (Robertson, 1998). But something was different this year....

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...

Cyclospora cayetanensis is a coccidian protozoa that was newly recognized in 1979 in Papua New Guinea. We report the case of a 42-year-old French man who had visited Vietnam and presented with fever and watery diarrhea that had lasted for more than 2 weeks. The patient was diagnosed with C. cayetanensis infection by examination of a stool smear using UV fluorescence microscopy. Based on this ra...

354 Letters To the Editor: The organism now named Cyclospora cayetanensis was first recognized as a cause of human illness in 1977. For several years, as its taxonomy was deliberated , it was referred to as " cyanobacterium-, or coccidia-like bodies " (CLBs), or considered to be blue-green algae. In 1993, C. cayetanensis was reported to be a protozoan parasite, a coccidian member of the family ...
