(L.) amazonensis promastigotes (6 parasites per macrophage) during 3 h and treated with hydroalcoholic extract of C. brasiliense (30 μg/mL) and infection index was obtained after 3 and 24 h of treatment. (b) Cultures were treated with C. brasiliense alcoholic extract (30 μg/mL) for 3 h then they were infected with L. (L.) amazonensis, and the infection index was obtained after 3 and 24 hours.
