GUARALDO, Ana Maria Aparecida; MAGALHAES, Luiz Augusto; RANGEL, Humberto de Araújo  and  PAREJA, Gilda. The evolution of sporocysts of Sehistosoma mansoni, Sambon, 1907, in Biomphalaria glabrata (Say, 1818) and in Biomphalaria tenagophila (D'Orbigny, 1835). Rev. Saúde Pública [online]. 1981, vol.15, n.4, pp.436-448. ISSN 1518-8787.

The evolution of sporocysts of Sehistosoma mansoni strains from BH and SJ in their respective vector snails was studied, and aspect and the number of the initial sporocysts were verified during the first weeks of infection. Significant differences were noticed in the number of sporocysts in both strains. Aspects of their development were observed, as well as their distribution throughout the organs, until the cercariae were completely formed.

Keywords : Sehistosoma mansoni; Biomphalaria glabrata; Biomphalaria tenagophila; Sporocysts.
