Biomphalaria pfeifferi (Krauss) and Bulinus truncatus (Audouin) were infected with schistosome parasites. Infected B. pfeifferi occurred in 5 (11.9%) while infected B. truncatus occurred in 2(4.8%) of the 42 sites surveyed. Snail infection was highest (6.2%) from May to July and lowest (3.0%) from February to April. The number of infected snails increased with density. The snail population peaked in June while the smallest number were collected in March. The seasonality of the snail population was attributed to changes in the rainfall pattern.

Pośrednie stadia przywr z rodzaju Schistosoma stwierdzono u Biomphalaria pfeifferi (Krauss) i Bulinus truncatus (Audouin). Zainfekowane okazy B. pfeifferi stwierdzono na 5 (11,9%), a B. truncatus na 2 (4,8%) z 42 badanych stanowisk. Stopień zainfekowania ślimaków był najwyższy w maju-czerwcu (6,2%), a najniższy od lutego do kwietnia (3%). Ilość zarażonych ślimaków rosła wraz z zagęszczeniem. Populacja ślimaków była najliczniejsza w czerwcu, a najmniej liczna w marcu. Sezonowe zmiany liczebności ślimaków były spowodowane sezonowością opadów.
