Planorbidic survey of the State of São Paulo, Brazil: 8th Administrative Region (great area of São José do Rio Preto)

Abstract

In order to know the distributional patterns of Basommatophoran snails in the State of São Paulo (Brazil), 85 "counties" in the area of S. José do Rio Preto were worked out during seven months (1982). Snails from 286 breeding places were collected and identified. Biomphalaria straminea, an intermediate host of S. mansoni, was found in four little ponds, in the neighbourhood of Altair and S. José do Rio Preto. It was concluded that schistosomiasis has little chance to spread out in the studied area.
