Resumo: Experiências de suscetibilidade com 1582 espécimes de Biomphalaria occidentalis, medindo 3-6 mm de diâmetro, de 10 localidades dos Estados de Mato Grosso, Mato Grosso do Sul, Paraná e São Paulo, expostos individualmente a cinco miracídios de Schistosoma mansoni (cepa S12), deram resultados negativos. Como controles foram usados exemplares de B. tenagophila de Joinville (Santa Catarina) e Taubaté (São Paulo), apresentaram índices de infecção de 17.9% e 14.8%, respectivamente. Estão em andamento experiências com outras cepas de S. mansoni. Se os resultados atuais forem confirmados, torna-se menos provável uma contribuição da B. occidentalis para a expansão da xistosomose em direção ao extremo oeste do Brasil.

B. tenagophila from Joinville (Santa Catarina) and Taubaté (São Paulo), used as controls, showed infection rates of 17.9% and 14.8%, respectively. Experiments with other strains of S. mansoni are in progress. If the present results are confirmed, expansion of schistosomiasis toward far-western Brazil through the agency of B. occidentalis becomes less probable.Fundação Oswaldo Cruz. Instituto Oswaldo Cruz.
