摘要
Schistosomiasis has expanded to southern parts of Brazil. Between 2005-2007 the dispersion and the proliferation of Biomphalaria tenagophila was verified in the province of Corrientes near the Brazilian border. In order to study the possibility that schistosomiasis might spread into the basins of the Parana and Uruguay Rivers, 440 B. tenagophila collected from 10 populations groups were experimentally exposed to infection with Schistosoma mansoni of the SJ(2) strain. Snails from five localities were susceptible. Frandsen's index (TCP/100) shows that those snails from Mirunga (11%), Aguacerito (2%) and Curupicay (2%) were Class land not very compatible. Meanwhile, snails from Copra (6%) and Pay-Ubre (22%), in the Parana River basin, were Class II and poorly compatible.
