Fig. 1 The in-vitro production of IL-6 in human adult whole blood after incubation for 4 h at 37 °C with live Streptococcus pneumoniae. Lo = serotypes 3 and 7F; Hi = serotypes 9V and 23F. Neg = negative control, i.e., whole blood incubated without S. pneumoniae; Pos 1 ng and 0.1 ng = positive controls, i.e., whole blood incubated with lipopolysaccharide 1 ng and 0.1 ng.

Fig. 2 The neutrophil oxidative burst response to live Streptococcus pneumoniae using human pooled serum with known concentrations of complement and serotype-specific immunoglobulin. The results are shown as a mean percentage (+ SE) of the maximal oxidative response in four experiments. PMNL, polymorphonuclear leukocytes; SP, S. pneumoniae; Po, pooled serum; Pi, pooled serum, heat inactivated.
