Figure 5

Light microscopy of E. granulosus protoscoleces incubated in vitro with thymol and essential oils of T. vulgaris and O. vulgare. (a) Control protoscoleces (cc: calcareous corpuscles, h: hooks, rr: rostellar region, s: suckers, and sr: soma region; 3 days p.i., 500x). (b)-(c) Note the presence of numerous blebs in the tegument of treated protoscoleces (arrows). (b) T. vulgaris (3 days p.i., 400x). (c) O. vulgare (3 days p.i., 500x). (d) Protoscoleces incubated with thymol during 2 days. The tegument was markedly altered (arrow). Note the loss of hooks (arrowheads, 400x).
