  This peripheral blood smear from the patient shows a higher power view of a Trypanosoma cruzi trypomastigote. Note the prominent kinetoplast (arrow).

• 

  This is a low-power photomicrograph of an H & E stained section from the heart biopsy of this patient. Note the organisms within a myocyte (arrow) and the adjacent inflammatory response.

• 

  This is a higher-power photomicrograph of an H & E stained heart biopsy from this patient. Again, note the organisms within a myocyte (arrow) and the inflammatory response.

• 

  This is a higher-power photomicrograph of an H & E stained heart biopsy from this patient. At this magnification the organisms within a myocyte (arrows) and the adjacent inflammatory response are more clearly seen. The individual organisms within the myocyte are called amastigotes.

• 

  This is a higher-power photomicrograph of an H & E stained heart biopsy from this patient. Note the T. cruzi amastigotes (arrows) within this longitudinal section of a myocyte.
