Graphical representation of the OD values for evaluation of the plasma IgG and intestinal lavage sIgA responses to JOL1587 immunization in chickens. I) Plasma IgG levels, II) Intestinal lavage sIgA levels. a: PBS-inoculated group; b: single immunized group and c: double immunized group. The arrow denotes the time of booster immunization in group C chickens. Values shown for each group are the mean ± SEM of antibody levels (n = 6). The * symbol indicates a significant increase in the antibody levels in the JOL1587 immunized chickens compared to the control group chickens (P ≤ 0.05)
