Kinetics of intracellular multiplication. HEp-2 cell
monolayers were infected for 3 h, and the number of intracellular
bacteria was determined after different times of gentamicin treatment.
Results are expressed as the number of intracellular bacteria relative
to that obtained at 1 h of gentamicin treatment, taken as 100%.
