Figure 5: Transmission electron microscopy of extract-treated protoscoleces. (a) Invaginated and (b) evaginated protoscoleces under light microscope. ((d)-(e)) represent corresponding TEM images of protoscoleces, showing complete tegumental damage by marked vacuolization of tegument layer. The distinct digitiform tegumental extensions ((f), (h)-(i)) were also observed under electron microscopy of extract-treated protoscoleces (marked with arrows), (g) corresponding well with normal microscopic view.
