Virulence and growth in IFN-α-R−/− mice. Groups of 6-week-old mice were infected, i.p., with 103 PFU of rMVEV, NS1-2A cleavage site mutants, or plaque size variants derived thereof, and morbidity and mortality recorded daily (a). At 2 days pi, serum was collected from infected mice and viremia titers determined by plaque assay on Vero cells (b). Each symbol represents an individual mouse, and mean titers are represented by a horizontal line. The interrupted line indicates the detection limit of the plaque assay
