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%. (A) ■, strain LF82; ▴, EPEC strain E2348/69. (B) ■, strain LF82; ○, EIEC strain E12860/0. Each point is the mean of at least three separate experiments.
