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%.
本文展示了一项寄生虫学调查的结果，该调查特别着重于曼氏血吸虫病。研究区域为位于雅库皮兰加市（巴西圣保罗州）卡贾蒂区，靠近里贝拉河谷血吸虫病流行区。尽管已有报告称存在曼氏血吸虫寄生人群，且已确定负责在该州大片区域传播寄生虫的物种——嗜气管双脐螺的疫源地，但尚未报告任何本地病例，也未发现感染血吸虫的扁卷螺。作为对该州扁卷螺名录的补充，报告了在该地区首次发现的物种 Drepanotrema cimex 和 D. depressissimum。在所研究人群的样本中检测抗弓形虫抗体，结果显示显著患病率为76.4%。
