Evaluation of In Vitro Activity of Essential Oils against Trypanosoma brucei brucei and Trypanosoma evansi
Effect of CS (a), ED (b), EC, (c) and CC (d) essential oils (EO) on T. evansi blood forms. The EOs were diluted at 0.4 g/mL (dark blue), 0.2 g/mL (red) and 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).
