Sobre o isolamento de uma cepa humana de Schistosoma mansoni, Sambon, 1907 / On the isolation of a human strain of Schistosoma mansoni, Sambon,1907

In this paper the authors briefly describe a human Schistosoma mansoni strain from Pará State, Brazil. The CIRENE'S strain was capable of infecting 71.4% of the snail vector Biomphalaria glabrata (Telegrafo's strain) provided by the "Evando Chagas" Institute, Belém. The cycle was completed by the infection of six mice. The thoracic and abdominal organs were examined microscopically which demonstrated the passage of the worm into the liver and lungs. The authors discuss the importance of these results in the epidemiology of schistosomiasis in Pará.
