Figure 3From: Construction of a Salmonella Gallinarum ghost as a novel inactivated vaccine candidate and its protective efficacy against fowl typhoid in chickensThe lymphocyte stimulation responses determined at 3-week-postimmunization against the sbcp Antigen. The stimulation index of lymphocyte sample from the chickens was determined by the peripheral lymphocyte activation assay. The values were considered statistically significant, if p values were ≤ 0.05 (*p ≤ 0.05). Group A, non-immunized control; group B, orally immunized; group C, immunized subcutaneously; group D, intramuscularly immunized.Back to article page
