FIG. 5.

Detection of viral RNA (by means of real-time qRT-PCR) in sera of SCID mice that had been infected via the intraperitoneal route with the MOD/YF17D chimeric virus (•), MOD (▴), and YF 17D (□). Sera from three mice were collected and pooled every third day after infection (✻, all mice died). Quantification of the viral RNA load was done in triplicate.
