Abstract Trypanosoma cruzi is the causative agent of Chagas disease. This parasite requires the intracellular niche
in order to proliferate and disseminate the infection. After invasion, T. cruzi resides temporarily in an acidic vacuole
which is lysed by a not well-understood mechanism. Transmission electron microscopy was used to describe the
process of T. cruzi escape from the parasitophorous vacuole over the time. Using HeLa (non-professional phagocytic
cells) as host cell, we observed that recently internalized parasites reside in a membrane-bounded vacuole. A few hours
later, the first sign of vacuole disruption appeared as membrane discontinuities. This observation was followed by a… More >
