Fig 2. Maternally acquired dengue-specific IgG and IgA antibody titers.

Fig 2

(A) DENV1-specific IgG and (B) cross-reactive DENV2-IgG titers in sera from 5-week old A129 mice (n = 4–6) born to and nursed by DENV1-immune (DD), or born to DENV1-immune mothers and nursed by naïve mothers (DN), or born to naïve mothers and nursed by DENV1-immune mothers (ND), or born to and nursed by naïve mothers (NN). **p<0.01 based on Mann-Whitney test comparing DN and ND with respect to DD control group. (C) DENV1-specific IgA titers in sera from 5-week old mice born to and nursed by DENV1-immune or naive mothers (n = 5). UD: Undetectable. (D) DENV1-specific IgG and IgA titers in pooled sera from mothers infected with DENV1 at week 2, 4, and 6 post-infection. Dotted line denotes the limit of detection of the assay.
