Abstract
The development of sporocysts of Schistosoma mansoni was monitored in pigmented and albino Biomphalaria glabrata from Puerto Rico and Brazil. The snails were exposed individually to 20 miracidia, and sporocysts were allowed to develop for 3 to 12 weeks. Most of the immature sporocysts were found in the seminal receptacle sac and vas deferens during development. In contrast, mature daughter sporocysts were detected everywhere except in the foot at 12 weeks after exposure to the miracidia. It was found that mature daughter sporocysts formed more rapidly in the pigmented than in the albino snails, but no difference was observed in the formative time between the same types of Puerto Rican and Brazilian snails. It seems likely that there is a correlation between the infection rate and the time required for formation of mature daughter sporocysts in B. glabrata.
