Effect of C. verum EO on T. cruzi intracellular amastigotes after treatment for 24 h

	% Infected cells	Total intracellular amastigotes	Amastigotes/cell (mean)	Density amastigotes/mm 2	AI a	%I b
Control	59 (n = 5812)	25746	7.52	42.7	442.5	-
10 μg/ml	51.8 (n = 5709)	20315	6.87	33.7	355.87	21.1
20 μg/ml	50.6 (n = 4946)	12717	5.08	21.1	257.05	50.61

^aAssociation Index (AI) =% infected cells × amastigotes/cell.

^b% Inhibition (%I) = 100 − (T/C × 100), where T is the total number of intracellular amastigotes in treated cells and C is the total number of intracellular amastigotes in control cells.
