Abstract

This study aims to assess the situation of urinary schistosomiasis in a suburban area of the city of Ouagadougou. A malacological survey followed by a parasitological survey was carried out within the schoolchild of Yamtenga . The malacological survey was to identify intermediates hosts of schistosomia­ sis in the dam of Yamtenga. And parasitological survey was carried out for the diagnosis of urinary schis­ tosomiasis. For the detection of eggs of Schistosoma haematobium filtration method of 1 Oml of urine was applied . The test of emission of cercariae by the snails was used in order to detect those snails which were naturally infected. The presence of Bulinus truncatus has been reported with a natural infection rate of 2.05%. A total of 323 school children were enrolled from two primary schools in this study. The prevalence of urinary schistosomiasis was 2.78%. Accord ing to the gender, the prevalence was 5.66% among males against 0% in the female (p=0.002).

The results showed that urinary schistosomiasis persists in the city of Ouagadougou but however with a

low prevalen ce. Malacological survey shows that Bulinus truncatus can be responsible of transmission of urinary schistosomiasis.
