Viability of ZIKV-infected cells. Vero, mOEC, hOEC and hCMEC/D3 cell lines were infected at an m.o.i. of 1 with (a) ZIKV MR766 or (b) BeH819015 or were mock-infected. At 1, 3, 5 and 10 days p.i. cell viability was determined by MTT assay. The obtained values were normalized to mock-infected cells (set as 1). Each bar represents the mean±sem of two independent experiments performed in triplicate. nd, not detectable; ***P<0.001. The viability of infected cells was compared to that of uninfected cells using two-way ANOVA with Bonferroni’s post-test (n=6).
