for routine light microscopy, while the left kidneys were prepared for transmission electron microscopy. The kidney in this animal is bean-shaped and has a smooth surface. Light microscopy analysis revealed that the renal corpuscles are small dark red...

. In light microscopy, 89 out of 100 cattle (89%) had thin-walled cysts of S. cruzi, while 21 out of them (21%) had thick-walled sarcocysts. In addition to light microscopy, ultrastructural features of the thin-walled cyst confirmed the presence of S. cruzi....
