Fig. 3From: Molluscicidal and parasiticidal activities of Eryngium triquetrum essential oil on Schistosoma mansoni and its intermediate snail host Biomphalaria glabrata, a double impactBiomphalaria glabrata eggs and embryos exposed to essential oil from Eryngium triquetrum. The data are presented as the mean ± standard deviation (SD). After 24 h of exposure to different concentrations of essential oil, egg hatching and snail development was monitored during 20 days. The term egg hatching corresponds here to a hatching leading to a normal development of the snail. This toxicity test was carried out twice on more than 25 egg masses per condition. Statistical significance was determined through Fisher exact test (P < 0.001). Asterisks indicate a significant difference between treated and non-treated eggsBack to article page
