[Parasitological survey, with special reference to schistosomiasis mansoni, conducted in the region of Jacupiranga (Ribeira valley, State of São Paulo). Survey of the location and distribution of planorbidian snails in the State of São Paulo. VII].
The results of a parasitological survey, emphasizing particularly schistosomiasis mansoni, are presented. The area under study was the district of Cajati, situated in the "município" of Jacupiranga (State of São Paulo, Brazil) near schistosomiasis-endemic areas in Vale do Ribeira. Though the presence of parasitized people by Schistosoma mansoni has been reported and focuses of Biomphalaria tenagophila, the species responsible for the spreading of the parasites through great areas of the state, has been localized, it has not been reported any autochthonous case nor the presence of schistosoma-infected planorbidian snails. As a contribution to the planorbidical chart of the State, it is reported as original the discovery of the species Drepanotrema cimex and D. depressissimum in that area. The detection of antitoxoplasmic antibodies in a sample of the studied population showed a significant prevalence rate corresponding to 76,4%.
