SLO and NADase are required for maximal survival of GAS in macrophages. Values are the mean numbers of CFU recovered immediately after 90 min of exposure to GAS (time zero) and 2 and 4 h later, expressed as a percentage of the value at time zero. Data for wild-type GAS strain 854 and the SLO-deficient Δslo mutant strain are shown in panel A and for clarity in panels B through F in comparison to those of individual mutant strains. Data represent the mean values ± the standard errors from at least four experiments performed in triplicate. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001.
