| Resumen: | The role of irrigated areas for the spread of schistosomiasis is of worldwide concern. The aim of the present studywas to investigate the spatial distribution of the intermediate snail host Biomphalariain an area highly endemic for schistosomiasis due to Schistosoma mansoni, evaluating the relationship between irrigation and types of natural water sourceson one hand, and the influence of place and time of water exposure on the intensity of human infection on the other. A geographical information system (GIS) was used to map the distribution of the intermediate snail hosts in Ilha das Flores,Sergipe, Brazil, combined with a clinical/epidemiological survey. We observed a direct correlation between the intensity ofhuman infection with S. mansoniand irrigation projects. Malacological studies to identify snail species and infection ratesshowed that B. glabrata is the main species responsible for human schistosomiasis in the municipality, but that B. stramineaalso plays a role. Our results provide evidence for a competitive selection between the two snail species in rice fields with apredominance of B. glabrata in irrigation systems and B. stramineain natural water sources. |
