Purpose: The present study was initiated to estimate the risk of Schistosoma haematobium expansion by assessing the susceptibility of Bulinus truncatus populations to Schistosoma haematobium.
Methods: Bulinus truncatus snails were harvested from three Cameroonian localities (Loum, Mbafam, Kekem) and one situated in Burkina Faso (Yamtenga). Once G1 samples constituted, they were divided into exposed and control groups and infested with two S. haematobium strains (Loum and Barombi-Kotto). The prepatent period, infection success rate and cercarial chronobiology were studied. Effects of S. haematobium infection on snail oviposition and mortality rates were also investigated.
Results: Results showed that all Cameroonian Bulinus truncatus populations were susceptible to S. haematobium. Their infection success rates varied from 75.5% to 6.3% between sympatric and allopatric couples (p
