Table 2.

Immunoglobulin titres (IgG plus IgM mean log titers and IgG2a/IgG1 log ratios) in mice, measured at week 4 after immunization with bacterins, either physically mixed just with EDA or bound to EDA (EDAvidin) by streptavidin-biotin (BEDA) interaction

^a Serum titre was defined as the reciprocal of the highest serum dilution showing a mean O.D. value equal to or higher than that of the negative control sera (n = 4) obtained from mice inoculated with PBS, plus 3 times the SD. Mean and SD (n = 4) represent the data obtained in triplicate.
