Figure 6: The ultrastructural damages observed with scanning electron microscopy when treated with extract of endophytic Pestalotiopsis sp. (a) The rosteller cone disorganization is prominently visible with remarkable damage in scolex and sucker region. (b) The damage at the surface teguments is also observed; loosening of hooks and microtriches was also observed at rosteller cone (c), total disorganization of hooks, and collapse of soma region. (d) The bursting of the soma region indicates the loss of tegumental integrity leading to osmoregulatory damage. (e) Enlarge view of hook, a typical shape characteristic for E. granulosus.
