[Susceptibility of Biomphalaria glabrata to Schistosoma mansoni from Venezuela and Brazil].
Schistosoma mansoni partially develops its life cycle into snails of the Family Planorbid. Biomphalaria glabrata represents an important host-intermediate. This paper reports experimental infection with miracidia vs. snail in sympatric and parapatric combination. The infection assay to sympatric combination were: BH snail (Belo Horizonte, Brasil) vs. a common geographic origin parasite, and Barbula, Carabobo State, Venezuela vs. SM Venezuela parasitic. The parapatric combination were: BH snail vs. SM; Barbula vs. BH; Caripe Monagas State, Venezuela vs. SM and Caripe vs. SM. During the study period was observed not miracid penetration. The infection percentage ranged from 88.89% in Barbula vs. SM combination to 0.00% in the Caripe vs. BH and BH vs. SM combination. We concluded which different existence of susceptibility from evaluated combination.
