Comparison of 125I-C3 binding to Campylobacter jejuni strains

aBacterial cells were incubated with pool 2 normal human serum or heat inactivated normal human serum and 125I-C3 (mean 40,416 [range 20,234-63,503]. cpm) at 37oC for 15 minutes. The cells were centrifuged and washed; net (NHS minus HINHS) 125I binding was measured as counts per minute. p-value = 0.20 (paired T-test, 1-tailed).
bThe mean binding ratio is an average of the ratio of the net counts for each study strain relative to the net counts of the serum-susceptible control (23B). p-value = 0.31 (paired T-test, 1-tailed).
