Fig. 4From: Molluscicidal and parasiticidal activities of Eryngium triquetrum essential oil on Schistosoma mansoni and its intermediate snail host Biomphalaria glabrata, a double impactMortality of free-swimming larvae of Schistosoma mansoni exposed to essential oil from Eryngium triquetrum. Results are presented as the mean ± standard deviation (SD) for at least 3 and 2 independent replicates for toxicity assays against miracidia and cercariae, respectively. About 300 miracidia and 100 cercariae were used for each independent experiment. The parasites (miracidia (a) and cercariae (b)) are considered dead if not mobile or motionless at the bottom of plates. Statistical significance was determined through Fisher exact test; “a” indicates a significant difference between the treated sample and the control, “b” indicates a significant difference between 1-h treated and 4-h treated parasitesBack to article page
