Fig. 3From: Bacillus subtilis spore vaccines displaying protective antigen induce functional antibodies and protective potencyAnti-PA antibody isotype profiles in serum from animals treated with different vaccine administration routes at 6 weeks post vaccination (6wpv). The serological responses were monitored, and the results at 6 wpv are presented. *, †, significant (P < 0.05 and P < 0.01) difference between groups at the same time point. Mean ± standard error.
