Brazilian Green Propolis: Effects In Vitro and In Vivo on Trypanosoma cruzi

Figure 4

Transmission electron microscopy (a–d) and scanning electron microscopy (e–g) of T. cruzi trypomastigotes treated with Et-Bra for 24 h: (a) control parasite with the normal morphology of mitochondrion (M), kinetoplast (k) and flagellum (f); (b) 30 μg mL⁻¹ and (c, d) 60 μg mL⁻¹ induced the formation of blebs on the body (arrow) and flagellar (arrowheads) membranes. Bars: 0.5 μm. (e) control parasite with the normal morphology; (f, g) 60 μg mL⁻¹ leading formation of blebs on the body (arrow) and flagellar (arrowheads) membranes and some rounded parasites (small arrow). Bars: 4 μm.
