Abstract
1. 1. The rectal biopsy technique was employed in the diagnosis of schistosomiasis. 2. 2. Of 38 patients passing ova of S. mansoni in the stool but with no ova of S. haematobium in the urine, 32 showed ova in the rectal snippings. Of these, 17 showed ova of S. mansoni alone, eight of S. mansoni and S. haematobium together (double infection), and seven of S. haematobium alone. 3. 3. Of 15 patients passing ova of S. haematobium in the urine but no S. mansoni in the stool, seven showed ova in the snippings. All seven showed ova of S. haematobium, whilst two of them contained ova of S. mansoni as well. 4. 4. Of 18 patients, in whom ova were found in neither the urine nor the stool, seven showed ova in the snippings, and of these, five showed ova of S. haematobium and two of S. mansoni. 5. 5. This method is of value not only in the recognition of S. mansoni but, in areas such as Rhodesia where S. haematobium is also endemic, it has an added advantage.
