The SEM imaging of adult R. hymenolepidoides, changes at 100 µg/mL conc. At different durations, (A,B,C At 30 min), (D,E,F At 60 min) and (G,H,I At 90 min). (A) Normal scolex appearance. (B) Minor breaks in immature proglottid striations. (C) Disorganization of mature proglottid striations. (D) Rostellum collapse with wrinkled, spineless suckers. (E) Multiple tegumental breaks in proglottids. (F) Severe distortion of tegument and segment borders. (G) Deep tegumental perforations. (H) Advanced tegumental detachment and breakage. (I) Evident digestion of the tegumental surface.
