Median virus neutralization values (%) of ZIKV per dilution and group, using liver homogenates from experimentally yellow fever virus-infected mice in adapted plaque reduction neutralization tests.

Legend: YFV: Yellow fever virus, ZIKV: Zika virus. Median virus neutralization values using liver homogenates in adapted plaque reduction neutralization assays are shown in percentages (results of triplicates). YFV-infected groups consisted of three mice. The negative control is liver homogenate obtained from uninfected animals (Neg), the positive control is sera from experimentally infected animal (pos 1), and the second positive control is composed of a mixture (1:1) of liver homogenate of uninfected animal and positive serum (pos2).
