Human PTX3 does not potentiate the lytic activity of complement towards Bt. Complexes of PTX3 and 10⁷ Bt were subjected to (a) 5%, (b) 10%, (c) 25%, or (d) 50% NHS, and bacterial CFUs were enumerated at 0, 2, or 6 h post-normal human serum exposure. Two-way ANOVA and Bonferroni multiple comparisons revealed no significant differences in CFUs between PTX3-bound or free bacteria. Each dataset is representative of n = 4 independent experiments
