| intervening transcribed spacer region 1 variability in cyclospora cayetanensis. | cyclospora cayetanensis is an apicomplexan protozoan parasite which has emerged as an important cause of epidemic and endemic diarrhea. water-borne as well as food-borne outbreaks have occurred, including a large number of u.s. cases associated with raspberries imported from guatemala. molecular markers exist for tracing the epidemiology of many of the bacterial pathogens associated with water-borne or food-borne diarrhea, such as serotyping and pulsed-field electrophoresis. however, there are c ... | 2000 | 10834999 |
| outbreak of cyclosporiasis associated with imported raspberries, philadelphia, pennsylvania, 2000. | 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 (multivariate relative risk, 5.9; 95% confidence interval, 3.6 to 10.5). leftover cake was positive for cyclospor ... | 2002 | 12141962 |
| cyclosporiasis: a point source outbreak acquired in guatemala. | cyclosporiasis is a disease due to cyclospora cayetanensis, an emerging coccidian parasite first described in 1979. it is an orally transmitted disease that is more frequent in tropical and subtropical areas. cyclospora cayetanensis has been mainly described as a cause of travelers' diarrhea. this pathogen has given rise to a number of epidemic outbreaks attributable to ingestion of imported foods, particularly from tropical areas. | 2006 | 17107425 |
| epidemiologic studies of cyclospora cayetanensis in guatemala. | in 1996 and 1997, cyclosporiasis outbreaks in north america were linked to eating guatemalan raspberries. we conducted a study in health-care facilities and among raspberry farm workers, as well as a case-control study, to assess risk factors for the disease in guatemala. from april 6, 1997, to march 19, 1998, 126 (2.3%) of 5, 552 surveillance specimens tested positive for cyclospora; prevalence peaked in june (6.7%). infection was most common among children 1.5 to 9 years old and among persons ... | 1999 | 10603209 |
| the return of cyclospora in 1997: another outbreak of cyclosporiasis in north america associated with imported raspberries. cyclospora working group. | in the spring of 1996, an outbreak of cyclosporiasis associated with fresh guatemalan raspberries occurred in the united states and canada. another multistate outbreak of cyclosporiasis occurred in north america in the spring of 1997. | 1999 | 10049199 |
| a foodborne outbreak of cyclosporiasis caused by imported raspberries. | cyclospora cayetanensis is a recently recognized parasite that causes prolonged diarrheal illness. its modes of transmission have not been fully determined, although some investigations before 1996 implicated water. outbreaks of cyclosporiasis in the united states in 1996 and 1997 are evidence of the increasing incidence of this disease. this report describes an outbreak of cyclosporiasis in persons who attended a luncheon on may 23, 1996, near charleston, south carolina. | 1998 | 9752377 |
| an outbreak in 1996 of cyclosporiasis associated with imported raspberries. the cyclospora working group. | cyclospora cayetanensis is a parasite that causes gastroenteritis. until last year most of the documented cases of cyclosporiasis in north america were in overseas travelers. in 1996, a large outbreak of cyclosporiasis occurred in north america. we investigated this outbreak. | 1997 | 9164810 |
| cyclospora cayetanensis in three populations at risk in guatemala. | in 1996 and 1997, outbreaks of cyclospora cayetanensis in north america were linked to guatemalan raspberries. from april 1999 to april 2000, we undertook a survey for c. cayetanensis in raspberry farm workers, malnourished children, and human immunodeficiency virus and aids patients in guatemala. stool samples were analyzed using ethylacetate-formalin concentration, wet preparation, modified acid-fast staining method, and epifluorescence. oocysts were found in 1.5% of the subjects, none of whom ... | 2001 | 11474019 |
