Figure 2: SEMs of the anterior end of adult Moniezia expansa.
(a, b) SEMs of normal fresh worm showing a globular scolex with four oval suckers and an elongated ribbon-like structure called strobila. (c, d) Following 24 h of incubation with 10 μg/ml ASO, showing wrinkled tegumental surface throughout the strobila. (e, f) Following 24 h of incubation with 50 μg/ml ASO. The scolex becomes more swollen than normal with narrowing of sucker’s opening. The proglottides appear deformed with circular areas of pronounced swelling occurred along their margins. (g, h) Following 24 h of incubation with 100 μg/ml ASO, showing shrunken scolex with severely distorted and folded tegument.
