Cellular immune response in ducklings immunized with pSCA1-E plasmid. a Specific proliferation of PBMCs in immunized ducks. The data are presented as the mean absorbance value of each group. b The interferon gamma (IFN- γ) concentration in serum from immunized ducklings was measure by ELISA. c The interleukin (IL-4) concentration in serum from immunized ducklings was measure by ELISA. Each data represents the mean ± SD. *P < 0.05, **P < 0.01 vs. PBS group; #P < 0.05 vs. inactivated HB strain group
