Attenuation of Simian Varicella Virus Infection by Enhanced Green Fluorescent Protein in Rhesus Macaques.

ABSTRACT: Simian varicella virus (SVV), the primate counterpart of varicella-zoster virus, causes varicella (chickenpox), establishes latency in ganglia, and reactivates to produce zoster. We previously demonstrated that a recombinant SVV expressing enhanced green fluorescent protein (rSVV.eGFP) is slightly attenuated both in culture and in infected monkeys. Here, we generated two additional recombinant SVVs to visualize infected cells in vitro and in vivo One harbors eGFP fused to the N terminus of open reading frame 9 (ORF9) (rSVV.eGFP-2a-ORF9), and another harbors eGFP fused to the C terminus of ORF66 (rSVV.eGFP-ORF66). Both recombinant viruses efficiently expressed eGFP in cultured cells. Both recombinant SVV infections in culture were comparable to that of wild-type SVV (SVV.wt). Unlike SVV.wt,
