Effect of ethanolic extract of Dalbergia sissoo plant parts on Biomphalaria alexandrina snail, the intermediate host of Schistosoma mansoni
This study evaluated, using replicated laboratory bioassays, the toxicities of the ethanolic extracts ofDalbergia sissoo (family Leguminosae) fruits, leaves, roots and stem bark against adult Biomphalaria alexandrina, the snail intermediate host of Schistosoma mansoni in Egypt and their egg masses. Adult snails (6 to 8 mm in diameter) and viable 24 h-old embryonated egg masses were separately exposed...

Impact of Euphorbia milii latex on infectivity of Schistosoma mansoni larval stages to their hosts
The effect of sublethal concentrations of Euphorbia milii latex on the infectivity of the larval stages ofSchistosoma mansoni to Biomphalaria alexandrina and to albino mice as well on these larval stages ofS. mansoni (miracidia and cercariae) were studied. The results showed that B. alexandrina infection with S. mansoni miracidia was greatly reduced by...
