Reaction of antibodies to Campylobacter jejuni and cytolethal distending toxin B with tissues and food antigens

Figure 4 Reaction of affinity-purified rabbit anti-Campylobacter jejuni cytolethal distending toxin with different food antigens. Compared to the reaction with Campylobacter jejuni (C. jejuni) antigens as positive control and HSA or unimmunized rabbit serum as negative control, the reaction of this antibody with 160 out of 180 food antigens is insignificant, and with 20 additional antigens ranges from low to very high. The variation of quadruplicate ODs was less than 10% for all determinations. Comparison of the means of the antibody reactivity to various food antigens with the means of controls resulted in insignificant values (P > 0.05) for 160 different food antigens and highly significant P values (P < 0.00001) for the other 20 antigens. E. coli: Escherichia coli; Cdt: Cytolethal distending toxin; LPS: Lipopolysaccharide; HSA: Human serum albumin.
