Effect of geranylgeraniol on macrophages interaction with Leishmania amazonensis after 24 h of treatment. Peritoneal macrophage cells were infected with promastigotes and treated with 1, 5, 10, or 25 μg/mL. Control group (untreated parasites) is also shown. The survival index was calculated by multiplying the percentage of macrophage cells with parasites and the mean number of internalized parasites per cell. The significant results (*P < 0.05) represent data from two independent experiments.
