The L. pneumophila clpP mutant Xp02 was degraded within 3 h of phagocytosis. J774A.1 cells were seeded in 24-well plates and infected with L. pneumophila at an MOI of 1. After 3 h, the survival of bacteria was determined by plating dilutions onto BCYE plates and calculating the numbers of CFU of L. pneumophila lysed from infected J774A.1. *, p < 0.05; **, p < 0.01. The phagocytosis assay was carried out in triplicate. Shown are the averages and standard deviations of three independent counts
