Zoonotic diseases, such as brucellosis, Q fever and Rift Valley fever (RVF) caused by Brucella spp., Coxiella burnetii and RVF virus, respectively, can have devastating effects on human, livestock, and wildlife health ...
molluscicidal and antimicrobial activity of solanum aculeastrum

Wanyonyi, Alphonse W.; Chhabra, S.C.; Mkojo, G.; Njue, Wilson N.; Tarus, Paul K. (2003)

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. ...
