Figure 2

Ultrastructural effect of copaiba oil after incubation for 72 h on promastigote and axenic amastigote forms of L. amazonensis, observed by transmission electron microscopy. (a) promastigote control; (b) promastigote treated with IC50 of copaiba oil; (c and d) promastigote treated with IC90 of copaiba oil; (e) amastigote, control; (f) amastigote treated with IC50 of copaiba oil; (g and h) amastigote treated with IC90 of copaiba oil. Bars = 1 μm. The treatment with copaiba oil led to changes in the mitochondria (m), exocytic activity in the region of the flagellar pocket (asterisk), and cytoplasmic vacuolisation (white star). n, nucleus; f, flagellum; fp, flagellar pocket; k, kinetoplast; m, mitochondrion.
