Electron microscope observations of Trypanosoma cruzi during development inside the haemocytes of Triatominae

The haemolymph of Panstrongylus megistus, infected by Trypanosoma cruzi, was examined by light and electron microscopy. Numerous parasites lie inside the haemocytes, each one in a vacuole. Their well-preserved morphological features support the concept of parasite multiplication in cells of the insect haemolymph.
