Cyclospora cayetanensis oocysts are detected in which specimen?

Explanation:
Cyclospora cayetanensis is an intestinal protozoan, and the oocysts are shed in feces. That makes stool the primary specimen for detection, typically by stool microscopy with a modified acid-fast stain to visualize the oocysts. Because shedding can be intermittent, testing several consecutive stool samples increases the chance of finding them. Blood, urine, or sputum are not appropriate for detecting Cyclospora oocysts since the parasite colonizes the intestinal tract and is not routinely present in those fluids.
