Interestingly, antiserum from mice immunized three times with the Alhydrogel formulation of Lpp:DbpAN40H6 had growth-inhibitory activity comparable to that of antiserum against other adjuvant formulations that elicited much higher total specific IgG levels measured by ELISA.Overall, there was a strong correlation between the protective efficacies of the various DbpA formulations and the in vitro g
