Scanning electron microscopy (SEM) of S. mansoni miracidia, unexposed miracidia showing: (A) cilia (C) covering the surface of the miracidium (→) (× 20000), (B) cilia (C) covering the miracidium (→) and extending from its lateral side (× 10000), (C) the apical papillae of the miracidium with its characteristic honey comb pattern of its terebratoria (→) (× 20000). Miracidium exposed to miltefosine showing: (D) loss of cilia from the surface of miracidium (× 20000), (E) protruded apical papillae with swollen oedematous corregated areas (× 10000), (F) higher magnification of (E) (× 20000).
