Figure 4. Cellular immune response in ducklings immunized with sigma C.

Figure 4

(A) The dynamic changes of lymphocyte proliferation in immune response test (A570 value). The lymphocyte proliferation response was measured on 2 weeks and 4 weeks after the first immunization. Each data represents the mean ± SD. **P < 0.01 vs. Bac-sigma C group stimulated with DMEM alone. ##p < 0.01 vs. NDRV-TH11 group stimulated with DMEM alone. (B) The interferon gamma (IFN-γ) concentration in serum harvested from immunized ducklings was measured by enzyme-linked immunosorbent assay (ELISA). (C) The interleukin 4 (IL-4) concentration in serum harvested from immunized ducklings was measured by ELISA. Data are the mean ± SD. *P < 0.05, **p < 0.01 vs. PBS group.
