Fig 4. DENV and ZIKV antibody dynamics.

Fig 4

iELISA and PRNT titers against DENV and ZIKV 28 days post-DENV inoculation (A-F), the day of ZIKV challenge (G-L), 28–35 days post-ZIKV challenge (M-Q), and the day of delivery (S-T). iELISA and PRNT titers from DENV-immune animals shown in orange and from DENV-naïve animals shown in blue. Samples labeled “ND” were not detected. Using an unpaired t-test, PRNT50, but not PRNT90, titers from the DENV-immune group were significantly higher than the PRNT50 titer of DENV-naïve animals at 28 days post-ZIKV-challenge (**p<0.01). Neutralization curves can be found in S1 Fig.
