Evaluation of In Vitro Activity of Essential Oils against Trypanosoma brucei brucei and Trypanosoma evansi

Figure 2

Effect of CS (a), ED (b), EC (c) and CC (d) essential oils (EO) on Tbb blood forms. The EOs were diluted at 0.4 g/mL (dark blue), 0.2 g/mL (red) or 0.1 g/mL (green) in pure vegetable oil as diluent and then added to the cultures, as described previously. Treatment of the parasites with Diminaveto (Positive control, purple) induced total lysis after 2 minutes. The number of parasites remained constant in negative controls and diluent control (light blue).
