Figure 3

Images at scanning electron microscope of E. granulosus (s.s.) protoscoleces treated in vitro with 100 μg/mL of S. aristata extract. Note untreated protoscoleces exhibiting an intact morphology both evaginated (a) or invaginated (b)-(c) Protoscolex incubated with 100 μg/mL of S. aristata extract for 2 days showing contraction of the soma region, extensive damage in the tegument, and loss of microtriches and hooks. (d) Protoscolex treated with 100 μg/mL of S. aristata extract for 10 days showed total loss of morphology.
