What color is the autofluorescence seen with Cyclospora cayetanensis?
The color depends on the particular FA filters used. If the filters are used for Calcofluor white, the oocysts will appear as pale blue rings; if the filters are used for FITC, the oocysts will appear to be more yellow-green. Fluorescence intensity will vary from about 1+ to 2+; it is rare to see stronger autofluorescence with these oocysts.
