AIF1 and infection: In agreement with previously published results [25], at this time point after infection, significantly higher levels of ZIKV RNA (Additional file 2: Fig. S2a) and Iba1 (a specific marker of microglial cells) labeling (Additional file 2: Fig. S2b) were observed in brain samples from ZIKV-infected CC071 compared to PBS-treated or ZIKV-infected CC001 mice.
