Answer to Case 551

Answer to Parasite Case of the Week 551: Cyclospora cayetanensis oocysts.

This is an unusual preparation in that we don't usually see C. cayetanensis oocysts in Giemsa-stained preparations. Therefore, confirmation using a conventional stain such as modified acid fast or modified safranin would be indicated. The diagnosis can be made by the shape and size (~8 micrometers) in diameter.

Thanks again to Florida Fan for sharing this interesting case!
