Antibody titers in mice immunized with the five differently adjuvanted vaccines. Blood samples were collected before vaccination and after the primary and secondary vaccinations. “ISA201 vaccine”, “Alh vaccine”, “IMS1313 vaccine”, “GEL vaccine” and “Oli vaccine” indicate that mice were subcutaneously immunized with the corresponding vaccine, respectively. “PBS control” indicates mice inoculated with sterile PBS buffer. The E. rhusiopathiae-specific antibody titers in the experimental and control groups were measured with an indirect ELISA and recorded at OD450. The error bars represent the SD.
