FIG. 5.

Role of bacterial virulence determinants for bacteria intracellular growth yields and recovery of amoebae. (A) Amounts of viable bacteria recovered from detached and attached A. rhysodes cells 16 h after infection. wt, wild type; Plasmid-, virulence plasmid cured. (B) Proportion of A. rhysodes cells recovered after infection with invasive (LB-grown) bacteria at the same time point. Values are means from three independent experiments, each carried out in duplicate wells. Error bars, standard deviations.
