Identification of mutations that aggravate the intracellular growth defect of Δsde. (A–C) BMDMs were challenged with WT (Lp02) or noted L. pneumophila mutants expressing luciferase (PahpC::lux). Intracellular growth was determined by measuring luminescence hourly. Data shown and error bars are mean ± SEM at 12 h increments (mean of three technical replicates and a representative of three biological replicates).
