Antibodies to BoHV-1 evaluated by ELISA in sera of cattle immunized with commercial reproductive vaccines applied simultaneously with Clostridial or FMD vaccines. Group 4 = vaccine D; group 5 = vaccine D + Clostridial vaccine; group 6 = vaccine D + FMD vaccine and Control group (not vaccinated). Mean titers ± standard errors (SEM) are shown. Letters (a, b, c and d) highlight significant differences (p < 0.05) between groups. A: Total IgG antibodies. B: IgG1 subclass antibodies. C: IgG2 subclass antibodies.
