a
Control experiments with E. coli DH5α resulted in secretion of 42.2 ± 16 pg of IL-8 per ml in 24 h.
b
ND, not determined.
c
Values are means and standard deviations from four experiments. For all values, P was <0.05 compared to a control experiment with E. coli DH5α.
d
Values are means and standard deviations from three experiments.
