Figure 1. Viremia and virus RNA detected in serum of rhesus and cynomolgus macaques after intravaginal inoculation with Zika virus. A) Rhesus macaques (animals R2 and R3 showed negative results); B) cynomolgus macaques (animals C1 and C2 showed negative results). Solid lines indicate virus titers in log10 PFU/mL. Dotted lines indicate genome copies in log10 copies/mL. The lower limit of detection was 1.0 log10 PFU/mL for virus titers and 3.0 log10 copies/mL for genome copies. C, cynomolgus; DPI, days postinoculation; R, rhesus.
