No freshwater snails were collected form the study area. The observed range of many physico-chemical factors was within the tolerance levels of the freshwater snails. The differences in the seasonal means of the parameters were not statistically significant. The absence of freshwater snails, including the snail vectors of schistosomiasis, was therefore attributed to the combined effect of the acidic nature of the water bodies and the low topographical terrain of the study area.

Na badanym terenie nie znaleziono żadnych ślimaków słodkowodnych. Wahania czynników fizykochemicznych mieściły się w granicach tolerancji ślimaków. Różnice pomiędzy średnimi sezonowymi były statystycznie nieistotne. Brak słodkowodnych ślimaków, w tym nosicieli schistosomiazy, był zatem wywołany łącznym wpływem niskiego pH i małej wysokości nad poziomem morza.
