	Unsporulated oocyst in early stages of sporulation during contraction of sporont (cytoplasm). The globules throughout the cytoplasm will gradually increase in number, fuse, and split into the refractile bodies
	Unsporulated oocyst in early stages of sporulation during contraction of sporont (cytoplasm). The globules have become more numerous throughout the cytoplasm will soon coalesce to form one large globule
	Unsporulated oocyst in early stages of sporulation during contraction of sporont (cytoplasm). The globules in the cytoplasm have coalesced to form one large globule
	Unsporulated oocyst. The large globule is now beginning to split into the refractile bodies
	Partially sporulated oocyst. The sporocyst walls have formed, but the sporozoites have not developed
	Fully sporulated oocyst with sporocysts. A small amount of oocyst residual material remains
	Fully sporulated oocyst compressed slightly due to coverslip pressure
	Unsporulated oocyst (slightly lower magnification than photos above) demonstrating autofluorescence at 340-380 nm (adapted from the CDC parasite image library)
