title: Cyclospora cayetanensis in three populations at risk in Guatemala.
abstract: 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 were raspberry farm workers.
