FIG 5

Effect of Pn3Pase treatment on complement-mediated killing by neutrophils. Shown is the complement-mediated killing capacity of differentiated HL-60 cells on Pn3Pase-treated S. pneumoniae. The percentage of survival was calculated as each duplicate reaction normalized to mean values obtained for control samples (where reactions without HL60 cells represent 100% survival). Statistical significance was determined with the two-tailed Student's t test. ***, P < 0.001; *, P < 0.05; ns, not significant.
