It was shown that these two compounds have no ovicidal effect on infective Ascaris ova in the concentrations used. Decortication of the Uva was observed in the first two concentrations of both test solutions. The motility and the hatchability of the contained larvae were also lowered in the higher concentrations of the test solutions.Medical SciencesParasitologyHelminthic diseasesAscariasisArticle
