In vitro invasion of human peritoneal macrophages with the ugp⁻ mutant. In vitro macrophage infection with C3-opsonized stationary phase wild type (circle) and ugp⁻ (square) promastigotes. The percentage of infected macrophages and the survival of parasite/30 macrophages as a function of time are shown in (A and B) respectively. The data represent the mean, minimum and maximum from three independent experiments. The inlay in A displays the P-value of the Welch two sample t-test for each time point
