Abstract | The susceptibility of Biomphalaria tenagophila from Espírito Santo (ES), Brazil was evaluated. Specimens F1 of B. tenagophila (ES) and B. glabrata (MG) control, were individually exposed to miracidia of the LE, SJ and AL strains. The snails were examined 30 days after the exposure and weekly thereafter for a period of 80 days. The snails that died during the experiment were subjected to the low-stringency polymerase chain reaction (LS-PCR) technique to detect Schistosoma mansoni DNA. The infection rate for B. tenagophila (ES) was 0% to all strains used, whereas the rates for B. glabrata were 81, 90 and 94.3% for the SJ, AL and LE strains, respectively. B. tenagophila snails that died during the experiments were not positive for S. mansoni, while all of the B. glabrata were positive for S. mansoni. In addition, to verify if the miracidia had penetrated in the molluscs and how long it was eliminated, B. tenagophila specimens were exposed to miracidia and ten snails were sacrificed at different times and subjected to LS-PCR. Forty-eight hours after the exposure, S. mansoni was not detected in B. tenagophila. We concluded that this B. tenagophila population is resistant to infections of S. mansoni (100 miracidia/snail) | en_US |
