Abstract
The surface topography and ultrastructural changes of Schistosoma mansoni worms developed from ultraviolet-irradiated cercariae were compared with those from non-irradiated cercariae. The tegument of worms developed from irradiated cercariae showed a variety of changes including the occurrence of oedemata and most of the tubercles being torn at the tip and having lost their spines on the dorsal surface of some male worms. In females, parts of the tegument were devoid of spines and surface lesions were present. The range and extent of these changes differed not only among individual worms but also between different regions of individual worms resulting in generalized deformities in those worms originating from irradiated cercariae.
