Antigen specific lymphocyte proliferative response in chickens on 28 days post immunization. Chicken PBMCs from immunized and control groups (n = 6) were stimulated with NDV virus (A), recombinant VP2 protein expressed in Saccharomyces cerevisiae (B), and concanavalin A (conA) as positive control. Lymphocyte proliferative response was measured and expressed as stimulation index. All the data presented as mean value ± standard error and Waller-Duncan as post-hoc test. Level not connected by same letter are significantly different (p < 0.01).
