The Importance of Definitive Diagnosis in Chronic Schistosomiasis, with Reference to Schistosoma haematobium

الملخص EN

Schistosomes are long-lived parasites, hence schistosomiasis is a chronic disease with severe long-term implications.

However, definitive diagnosis of active infection has been difficult because demonstration of infection has depended on detecting parasite eggs in urine and/or stool.

In the case of Schistosoma haematobium which parasitizes the urinogenital system, this method has low sensitivity in adults.

Detection of parasite-specific DNA in urine has been demonstrated and this has similar specificity but improved sensitivity.

The implications of this new procedure and the impact on diagnosis are discussed.
