Serological immune responses in guinea pigs immunized i.d. with chimera. Animals (24/group) were immunized i.d. on days 0, 21, 42, and 63 with 13 μg chimera with or without 0.1 μg LT(R192G), 25 μg dsc19CfaE with or without 0.1 μg LT(R192G), or PBS. (A) Anti-CfaE IgG antibody responses (mean ± SD); (B) functional antibody titers measured by the HAI assay (median ± interquartile ranges); (C) anti-LTB IgG antibody response (mean ± SD). Horizontal dotted lines denote the limit of detection of the assays. Statistical significance was determined by using one-way ANOVA and Tukey’s post hoc test.
