Experiments were conducted to evaluate the mo activity of aqueous leaf and stem-bark extract of Pe Euphorbiaceae) Lymnaea (Radix) acuminata (Lamar (Deshyas) – intermediate hosts of endemic schistosom cattle and livestock. The toxic effect of both extracts wa There was a significant negative correlation between observed, thus the LC10 values of P. tithymaloide leaf de 15.4 mg/L (96 h); LC50 decr...

Freshwater snails of the genus Biomphalaria are important intermediate snail hosts for the widespread transmission of schistosomiasis in humans. This chronic and debilitating disease remains one of the most intractable public health concerns in 74 developing countries, infecting more than 200 million people. Prevalence of schistosomiasis is difficult to estimate, but according to the World Heal...

The present study was performed to observe histopathological changes in tissues of Bithynia siamensis goniomphalos (Gastropoda, Bithyniidae) incubated in crude extract solutions of camellia (Camellia oleifera) seed and mangosteen (Garcinia mangostana) pericarp, and furthermore to estimate the molluscicidal effects of 2 plant substances. Substantial numbers of bithyniid snails were incubated in ...

BACKGROUND Despite control efforts, human schistosomiasis remains prevalent throughout Africa, Asia, and South America. The global schistosomiasis burden has changed little since the new anthelmintic drug, praziquantel, promised widespread control. METHODOLOGY We evaluated large-scale schistosomiasis control attempts over the past century and across the globe by identifying factors that predi...

Fasciolosis is a water and food-borne disease caused by the liver fluke Fasciola hepatica and Fasciola gigantica. This disease is widespread in different parts of the world. Lymnaeidae and Planorbidae snails are the intermediate hosts of these flukes. Snail population management is a good tool to control fasciolosis because gastropods represent the weakest link in the life-cycle of trematodes. ...

Following the positive results obtained regarding the molluscicidal properties of the latex of Euphorbia splendens that were corroborated in laboratory and field tests under restricted conditions, a field study was conducted in experimental streams located in an endemic area. After recording the average annual fluctuations of vectors in three streams, a solution of E. splendens latex at 12 ppm ...
