a) Blood film showing numerous erythrocytes that contain intracytoplasmic protozoan gametes, including small dark bodies (long arrow), ring forms (short arrow), and elongated forms (arrowheads). Wright-Giemsa, bar = 25 μm. b) Megaloschizont filling lumen of a blood vessel in the smooth muscle tunic of the ventriculus. Note clear vacuole, proteinaceous fluid (*), and zoites. HE, bar = 220 μm. c) Degenerative cyst in ventricular smooth muscle tunic. Note that the remnant cyst contains proteinaceous fluid (*) of the parasite admixed with host erythrocytes. HE, bar = 190 μm. d) Focus of mixed inflammation and hemorrhage following megaloschizont rupture and vascular obliteration. HE, bar = 210 μm.
