Alguns dados referentes ao estudo parasitológico e anatomopatológico de duas linhagens de Schistosoma mansoni Sambon, 1907 Some data regarding the parasitological and anatomopathological studies of two strains of Schistosoma mansoni Sambon, 1907

Foi estudada a ação patogênica das linhagens de Schistosoma mansoni dos municípios de Belo Horizonte, MG e de São José dos Campos, SP (Brasil) observando maior capacidade patogênica da linhagem do primeiro, nas condições da experiência.An experiment was carried out in order to determine differences in the pathology of two S. mansoni strains, one from the state of Minas Gerais (Belo Horizonte) and the other from the State of S. Paulo (S. José dos Campos), Brazil. Mice were infected with both strains under experimental conditions and the comparative study of these animals showed significant differences as regards pathology of the tissue lesions. The Belo Horizonte strain showed a higher level of pathogenicity when compared to the S. José dos Campos one.
