Stimulation indices for measurement of a lymphocyte proliferation response in the JOL1587-immunized and control group chickens. a PBS-inoculated group; b Single immunized group and c: Double immunized group. The LPA assay was performed at 7 and 11 weeks of age after the prime and booster immunizations, respectively. The * symbol indicates a significant increase in the lymphocyte proliferation response in the JOL1587 immunized chickens compared to the control group chickens (P ≤ 0.05). Total six samples were analyzed which were collected from six randomly selected chickens from group a, b and c
