Fig 7. Cattle immunogenicity studies using the HS-PmSLP vaccine.
Ai, B: HS-PmSLP antigen specific IgG detected in serum of cattle from Trials 3 and 4 respectively. Aii: Cross-reactivity of serum from Trial 3 against BRD-PmSLP protein. (Left) Background subtracted absorbance readings obtained for each animal using serially diluted serum. Dotted line represents the cut-off used for calculating IgG titre. (Right) Boxplot displaying individual animals. 2-way ANOVA with Dunnett’s multiple comparisons test performed on log2 transformed data to compare post vaccination titres to baseline. * p<0.05, ** p<0.01, ****p<0.0001, ns = not significant. Vaccine 1 formulated with Montanide Gel02 + Poly(I:C), Vaccine 2 formulated with Alhydrogel. Adjuvant controls received Montanide Gel02 + Poly (I:C) only.
