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 were raspberry farm workers.
