(c) Immunohistochemistry identifies a Trypanosoma evansi trypomastigote in the brain of a horse; Avidin-biotin-peroxidase complex, 1000×, Bar = 10 μm. (d) Sarcocystis neurona merozoites within the brain of a horse; HE, 1000×, Bar = 10 μm. (e) Neospora spp. tissue cyst in the brain of a dog; HE, 1000×, Bar = 10 μm.
