The effects of population density on growth and reproduction of Biomphalaria
glabrata (Say) (Gastropoda: Pulmonata).

Throughout sub-Saharan Africa, Biomphalaria
pfeifferi snails are freshwater intermediate hosts for Schistosoma mansoni blood flukes, which cause intestinal schistosomiasis (1).
Structure of the extracellular hemoglobin of Biomphalaria
These included Bithynia siamensis of the family Bithyniidae  and array of other snail genera like Biomphalaria
, Bulinus, Ceratophallus, Gabbiella, Gyraulus, and Melanoides .
Data in Table 1 contain a comparison of the shrimp-deduced proteins with the homologous proteins from other marine invertebrates, including crustaceans as the copepods Tigriopus californicus and Lepeophtheirus salmonis, the crayfish Marsupenaeus japonicus, the water flea Daphnia pulex, the crab Eriocheir sinensis, and several species of molluscs (Lingula anatina, Crassostrea gigas, Biomphalaria
glabrata, and Aplysia californica).
In this scenario, the purpose of this work was to develop a new technique to assess the toxic effects of synthetic substances, extracts, fractions, and compounds isolated from plants of Biomphalaria
Total protein composition of young and adult Biomphalaria
alexandrina snails with different compatibilities to Schistosoma mansoni infection
glabrata Say, 1818, resulting from the action of the saponins of these plants (SILVA et al., 2008).
mansoni (BH strain Belo Horizonte, Brazil) worms were maintained in Biomphalaria
glabrata snails as intermediate hosts and Mesocricetus auratus hamsters as definitive host at the Adolfo Lutz Institute (Sao Paulo, Brazil), according to standard procedures previously described (de Moraes et al.
Hematoporphrin was even found to be effective against the snail, Biomphalaria
alexandrina (ElHommossany et al.
