Fig. 8From: Comparative histochemical study of four enzyme activities on some organs of male Schistosoma mansoni and S. haematobiumLight micrographs of control and enzyme activity of male S. haematobium. a Control whole mount for 5′-nucleotidase activity. b Whole mount stained for 5′-nucleotidase activity. Note the positive reaction in the gynaecophoral canal edge (GCE), intestine (In), oesphagus (OE) and oral sucker (OS). c Magnification of the body showing a positive reaction in the gynaecophoral canal edge (GCE) and tegumental folds (TF). d Magnification of the body showing a positive reaction in the intestine (In) and muscles fibers (head arrow)Back to article page
