Figure 4

Scanning electron microscopy (SEM) of Schistosoma mansoni cercariae: normal cercaria showing: (A) cercarial body (B) and tail (T) with its two furculae (F), covered with glycocalyx (G) (× 1000), (B) tegumental folds (F) at the most anterior part of the head and evident tubular profiles (P) (× 15000), (C) numerous spines (S) covering the body region which are directed posteriorly and are covered with a glycocalyx that obscured these spines (× 20000), (D) the cercarial tail with its two furculae covered with glycocalyx (G) identical to that seen on the body but the tips of the spines (S) were often visible, larger and sharper than those of the body (× 7500). Cercaria exposed to miltefosine showing: (E) partial detachment of the body from the tail (→) with marked loss of the glycocalyx, thining of the tegument (→) and surface blebbing (× 1000), (F) separated cercarial body (× 2000), (G) surface blebbing of the tegument (B) (× 2000, inset × 15000). (H) focal loss of tegumental spines (→) (× 20000).
