Viral kinetics of ZIKA–WT and ZIKA–EGFP in Vero cells. Vero cells were infected with ZIKA–WT and ZIKA–EGFP, and a intracellular viral RNA expression was detected at various time points by qPCR. b Viral titer in culture supernatant was determined by TCID₅₀ assay. All experiments were repeated three times and each group contained three replicates
