Resumo: The viability of Schistosoma mansoni miracidia in host molluscs, obtained from two origins is examined: from eggs eliminated with feces of the definitive hosts and liver granuloma eggs. The effect of the origin of the miracidia on the number of cercariae and on the time of cercariae elimination was investigated. The prepatent period of cercariae elimination, snail survival after infection and the sex of the eliminated cercariae were also observed. The following results were obtained: a) snails infected with miracidia from liver granuloma eggs took longer to begin to eliminate cercariae; b) snail survival after infection was longer in the group infected with miracidia from liver granuloma eggs; c) the total number of cercariae produced by the snail group infected with miracidia from liver granuloma eggs was three times that of the group infected with miracidia from eggs eliminated with feces.

Estudou-se comparativamente a viabilidade, em moluscos hospedeiros, de miracídios de Schistosoma mansoni de duas origens: de ovos eliminados com as fezes e de granulomas hepáticos. Procurou-se saber se havia efeito da origem sobre o número total de cercárias obtidas e sobre o período de eliminação de cercárias. Foram também verificados o período pré-patente da infecção dos moluscos, a sobrevivência do caramujo após a infecção e o sexo das cercárias eliminadas. Concluiu-se que: a) o período pré-patente foi maior nos moluscos infectados por miracídios provenientes de granulomas hepáticos; b) a sobrevivência dos moluscos após a infecção foi maior naqueles infectados por miracídios provenientes de granulomas hepáticos; c) o número de cercadas eliminadas por molusco infectado com miracídios provenientes de granulomas hepáticos foi três vezes maior que o número de cercárias eliminadas por moluscos infectados com miracídios provenientes de ovos eliminados com as fezes.
