Abstract

The three main species of trematode flukes which cause schistosomiasis are Schistosoma japonicum, S. mansoni, and S. haematobium. The diagnosis is confirmed by demonstrating ova in the stools, rectal mucosa or urine, and the usual criterion of cure is the continued absence of eggs on repeated examination. The infestation is more easily treated than the complications of the disease. Organic antimony compounds have been used for many years but recently new drugs have become available. Dosage is usually based on body weight.
