Figure 5From: The effect of O-antigen length determinant wzz on the immunogenicity of Salmonella Typhimurium for Escherichia coli O2 O-polysaccharides deliveryImmune protective evaluation in birds. A Antibody level detection, B Survival rate, C mRNA level of cytokines elicited in immunization group, the cytokine stimulation index (SI) was expressed relative to the percentage of IL-2, IL-4, IL-10 and IFN-γ mRNA level in the BSG-treated group. Data were analyzed (n = 5) by t-test. *P < 0.05, **P < 0.01, NS = not significant. Error bars represent the standard deviation of 5 replicate samples.Back to article page
