Immunogenicity of CPSXiv-CRM197 in comparison with CPSXn-CRM197. (a) Vaccination schedule showing the immunisation and bleeding of mice. (b) The anti-CPSX IgG ELISA used to determine immunisation results demonstrated comparable IgG responses to CPSX with both, the synthetic (CPSXiv-CRM197) and the benchmark (CPSXn-CRM197) vaccine. Each symbol represents an individual animal. The horizontal bars indicate the geometric mean titre and 95% confidence intervals. *Significant differences between the indicated groups with P<0.05 (CPSXn-CRM197: P=0.028, CPSXiv-CRM197: P=0.0284; Mann-Whitney test). CPSX, NmX capsule polysaccharide; CPSXiv, in vitro produced CPSX; CPSXn, CPSX obtained from natural source; IgG, immunoglobulin G.
