Relative translocation of internalized S. pneumoniae when the lysosomal function is inhibited with NH₄Cl.

Translocation in the presence of the vehicle of the inhibitor is set at 100%, and translocation in experimental conditions is related to this percentage. O designates the relative invasion in one individual experiment, ― is the average of all experiments. (n = 6), p.<0.05. Translocation was defined as the cumulative number of bacteria obtained in the lower compartment over 5 hours divided by the number of bacteria obtained at initial invasion point.
