The molluscicidal properties of Solanum nigrum L. were tested against three Egyptian snail species (Biomphalaria alexandrina, Bulinus truncatus and Lymnaea natalensis), each an intermediate host of parasites causing human schistosomiasis or fascioliasis. The plant was collected in two regions within
Schistosomiasis is a chronic disease caused by trematode flatworms of the genus Schistosoma; it accounts for more than 280,000 deaths annually. In this work we investigated the effect of the alkaloidic extract obtained by acid-base extraction of the dried fruits of Solanum lycocarpum on
A crude water extract of Solanum nigrum leaves was used as a chemical attenuate to Schistosoma mansoni cercariae prior to infection of Swiss female mice. Cercariae were exposed to 2.5, 5, 7.5 and 10 mg/l concentrations of the extract for 30 min. The effect on the ability of cercariae to penetrate
Schistosomiasis is the most noteworthy parasitic disease after malaria. Furthermore, the significant activity of the genus Solanum against Schistosoma worms and its intermediate host snails reinforced the study of Solanum seaforthianum Andr. (SS) and Solanum macrocarpon L. (SM) for their
Solanum nigrum L. leaves and fruits were shown to have molluscicidal activities against snails transmitting schistosomiasis and fascioliasis. In the present study, their molluscicidal activity against adult Biomphalaria alexandrina snails was assessed to determine whether plants collected at various
The methanolic extract of the fresh root bark and berries of Solanum aculeastrum showed significant activity against host snails of schistosomiasis. The berries extract was more potent with 100% snail kill at 50 ppm. Fractionation increased activity with 100% mortality at 20 ppm. The aqueous and
Aqueous suspensions of powder of sun- or freeze-dried berries of the plant Solanum aculeatum (Family Solanaceae), indigenous in Kenya, were tested for molluscicidal activity against Biomphalaria pfeifferi, Bulinus globosus and Lymnaea natalensis under laboratory conditions. One hundred or 50 mg
Schistosomiasis is one of the most important human parasitic diseases. One of the possible methods for the control is through the molluscan intermediate host of the parasite. Biomphalaria arabica, molluscan hosts to Schistosoma mansoni in Saudi Arabia were treated with sublethal concentrations
The importance of the glycolytic flux for the success of Biomphalaria-Schistosome sporocyst interaction was acertained in this study. Hexokinase (HK), pyruvate kinase(PK), glucose phosphate isomerase(GPI) and lactate dehydrogenase (LD) as four important glycolytic enzymes were markedly stimulated in
Overall, 173 tropical plants from 72 different families, collected from the north-western and western regions of Puerto Rico, were screened for their molluscicidal properties against Biomphalaria glabrata, the intermediate host of Schistosoma mansoni. Six plant extracts were effective at 50 ppm. The
