In Vitro Anthelminthic Activity and Ultrastructural Analysis of Barbatic Acid against Schistosomulae and Juvenile Worms of Schistosoma mansoni.

Schistosomiasis affects about 260 million people worldwide and the search for new schistosomicidal compounds is urgent. In this study we evaluated the in vitro effect of barbatic acid against schistosomulae and young worms of Schistosoma mansoni. The barbatic acid was evaluated through the bioassay of motility and mortality, cellular viability and ultrastructural analysis of juvenile stages through Scanning Electron Microscopy.

Toxicological effects of Ramalina aspera (lichen) on Biomphalaria glabrata snails and Schistosoma mansoni cercariae.

In this study, the molluscicidal activities against Biomphalaria glabrata and cercaricidal activities against Schistosoma mansoni of the ether extract of Ramalina aspera were evaluated. Additionally, toxicity parameters were evaluated at sublethal doses in terms of the influence of the extract on the fertility and fecundity of snails, as well as morphological alterations and quantification of their immunological cells. A test with Artemia salina was also carried out, in order to verify the environmental toxicity of the compound.

Dataset on schistosomiasis control using potassium usnate against at different developmental stage and cercariae.

This text presents complementary data corresponding to schistosomiasis mansoni׳s vector control and toxicity on cercariae using potassium usnate. This information support our research article "Potassium Usnate Toxicity Against Embryonic Stages of the Snail and Cercariae" [1], and focuses on the analysis of the detailed data regarding the different concentrations of potassium usnate and their efficiency to mortality and non-viability and cercariae mortality etiologic agent of the disease.

Dataset on usnic acid from Vainio (Lichen) schistosomiasis mansoni's vector control and environmental toxicity.

This text presents complementary data corresponding to schistosomiasis mansoni's vector control and enviromental toxicity using usnic acid. These informations support our research article "Toxicity of Usnic Acid from (Lichen) to embryos and adults of " by Araújo et al. [1], and focuses on the analysis of the detailed data regarding the different concentrations of Usnic Acid and their efficiency to mortality and non-viability, as also to environmental toxicity, evaluated by mortality.

Barbatic Acid Offers a New Possibility for Control of Biomphalaria Glabrata and Schistosomiasis.

This study evaluated the biological activity of an ether extract and barbatic acid (BAR) from on embryos and adult mollusks of , cercariae of and the microcrustacean . The ether extract and BAR were obtained by successive extractions with diethyl ether. The obtained extracts were analyzed using thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), proton nuclear magnetic resonance (¹H-NMR) and infrared (IR) spectroscopy.
