Humoral response to immunisation. Antibody titers were evaluated by ELISA, using HKEc P4 strain as antigen. Results obtained before immunisation (I0) and 2 weeks after the booster immunization (R14) are presented for the adjuvant only (Control), intramuscular (IM) and intramuscular and intramammary (IMM) groups. (a) antibody titers in the IgM isotype; (b) antibody titers in the IgG2 sub-isotype. *p < 0.05, **p < 0.01, Friedman test and post hoc Dunn’s multiple comparison test.
