Abstract
INTRODUCTION:
Biomphalaria snails may display varying levels of
susceptibility to Schistosoma mansoni infection. We have
been developing an in vitro model to study the interaction
between the snail and the parasite, using tissue-derived cell cultures from
Biomphalaria.
METHODS:
The digestive gland- and kidney-derived cells from primary cultures of
resistant (B. tenagophila Taim) and susceptible (B.
tenagophila HM and B. glabrata BH) strains of
Biomphalaria were exposed to S.
mansoni sporocysts.
RESULTS:
S. mansoni sporocysts were surrounded and encapsulated
exclusively by cells derived from the digestive gland (DG) of B.
tenagophila Taim. The process was followed by a marked decrease
in the number of free sporocysts in the culture medium. The morphological
characteristics of DG-derived cells in culture have been described.
CONCLUSIONS:
Cells derived from DG (but not SK) primary cultures of B.
tenagophila Taim may participate in S. mansoni
sporocyst control.
