Figures & Tables

Fig. 1.

The observed percentage of unhatched eggs, larvae of the first and second stage (L1-L2) and larvae of the third stage (L3; percentage development) of Haemonchus contortus, Trichostrongylus spp. and Oesophagostomum spp. at increasing dimethyl sulfoxide (DMSO) concentrations. Dots – arithmetic means; whiskers – 95% confidence intervals; asterisks (*) – statistically significantly lower percentages than in the control wells according to Dunnett’s test at α = 0.05

Fig. 2.

The five-parameter logistic curve (blue line) fitted to the observed percentage development of larvae of the third stage (L3) of Haemonchus contortus, Trichostrongylus spp. and Oesophagostomum spp. at increasing dimethyl sulfoxide (DMSO) concentrations. Red dots – exact values of tested concentrations indicated. Orange broken lines and arrows – DMSO concentrations inhibiting the development of 10%, 50% and 90% of L3
