The present study was undertaken to investigate the lethal activity of chlorophyllin against different developmental stages of Biomphalaria alexandrina snails and Schistosoma mansoni aquatic larvae under laboratory conditions. In all experiments, the studied organisms were incubated in different chlorophyllin concentrations in the dark, and then exposed to sunlight to stimulate the lethal photosensitizing action of chlorophyllin. | Effect of chlorophyllin on Biomphalaria alexandrina snails and Schistosoma mansoni larvae
